That which was mentioned in the section above were the essential requirements of tawbah. There are certain conditions for its acceptance, as well as for its perfection, that we shall mention below.
The main conditions for the acceptance of tawbah are two. So also there are two main conditions for its perfection. In this section we shall mention the noble utterance of Hadrat Mawla al-Mawali, 'Ali ibn Abi Talib (A), for, in fact, it is the essence of wisdom, being of the order of `speech of kings and king of speech':
It is narrated by al Sayyid al Radi - may God be pleased with him - in the Nahj al balaghah that some said 'Astaghfirullah (I seek God's forgiveness) before 'Ali (A). 'Ali said to him. "May thy mother mourn for thee! Do you know what is istighfar? Verily istighfar is a degree of the 'illiyyun and it is a word that means six things. First is remorse over the past. Second, the resolution not to return to it ever. Third, to return to the creatures their rights (usurped in the past) so that you meet God Almighty in such a state of purity that no one has a claim against you. Fourth, that you fulfil every duty that was neglected(derelict) by you, in order to satisfy your obligation in respect of it. Fifth, that you attend to the flesh of your body that had grown on unlawful nourishment so that it melts away as a result of grief and mourning and the skin adheres to the bones, after which new flesh grows there between. Sixth, that you make your body taste the pain of obedience in the same way as it tasted earlier the pleasure of sinfulness. When you have done these things then say Astaghfirullah! [4]
This noble tradition mentions firstly two essential requirements of penitence, which are remorse and the resolution not to relapse into sin. Then it mentions the two important(remarkable) condition for its acceptance, which are returning the rights of creatures and then of the Creator. Tawbah is not accepted from anyone on the mere verbal declaration, 'I repent.' The penitent man is one who returns everything illegitimately taken from others. If anyone has a claim against him, he should satisfy it if possible, or his propitiation. He should discharge whatever divine obligations and duties that have remained unfulfilled, and if all of them cannot possibly be fulfilled he should try to make amends to the extent that he can. He should know that everyone of these is a claim with a claimant that would demand it of him in the other life in the hardest of conditions, and he would be unable to satisfy it without taking up the burden of others' sins and exchanging his good deeds for the satisfaction of those claims. At that time, he will be helpless and destitute and have no way out for his relief.
My dear, let not Satan and the carnal self take hold of you and make the matter appear an unsurmountable difficulty in your eyes and thus finish you off by making you refrain from tawbah. Do know that it is better to act in this regard even if to a small extent. If the unoffered prayers, fasts and atonements are many, if God's unfulfilled duties are numerous and the people's usurped rights are innumerable, if your sins are abundant and your vices are plenty, do not despair of God's grace and' do not lose hope in His mercy. God Almighty will facilitate your passage if you act to the extent of your capacity and He will show you the path of salvation. You should know that to despair of the mercy of God is the biggest of sins and I don't think that any other sin has a more evil effect upon the soul. A person that despairs of divine mercy, his heart is so full of gloom and he becomes so unbridled that nothing can correct him. Beware, lest you despair of God's mercy and consider sins and their consequences as unsurmountable. God's mercy is greater than everything and encompasses all things, and God's justice is not bound by conditions. What were you, to begin with? In the void of nothingness, when there was no question of capacity or worthiness, God, the Supreme and the Glorious, endowed you with the bounty of being and the excellences of existence without any request or prayer or any worthiness or capacity on your part. Then He provided you with His unlimited bounties and His unending favours, subjecting all the creatures to you. Even now your condition is not worse than absolute nothingness and pure non-being. Moreover, God has promised mercy and forgiveness. Take a step forward(onward) towards His Holy threshold and He will Himself assist you by all means. If you cannot make amends for the return of His rights, He will overlook your failure. If you cannot satisfy the rights of others, He will compensate for it. And you have already heard the story of the young grave-opener during the times of the Messenger of Allah - upon whom and whose Progeny be God's benedictions.
My dear, the path of God is easy and simple. All that it requires is some attentiveness. Postponement, delay, neglect and allowing the sins to pile up day after day is what makes the matter difficult. But resolute action and decision to set aright the affairs of the soul makes the path shorter and the task easier. Make an experiment by taking some action. If you achieve results, the truth of this matter will be proved to you. Otherwise the path of perversion is open and the hands of your sinfulness are long.
The other two things mentioned by Amir al-Mu'minin (A) are the conditions for a perfect tawbah and a thorough penitence. Not that tawbah is not realized or accepted without them, rather it does not become perfect in their absence.
Let it be known to you that everyone of the stations (manazil) of the wayfarers has stages (maratib)which differ in accordance with the state of their hearts. If the penitent person wants to attain to its perfect degree, after having attended to the omissions - i.e. after having made good for the neglect of the duties-he should now attend to the accretions also. That is, he must now take up the spiritual accretion d during the days of sinfulness. That takes place by completely wiping out the physical and spiritual effects produced in the realm of the self so that the soul recovers its former refinement and its primordial, natural spirituality by a process of thorough purification. As you already know, every sin and pleasure produces an effect upon the soul in the same way as the body too derives nourishment from some of them. Hence the penitent person should with manly courage and determination exterminate all those effects and their traces through physical and spiritual austerities, as taught by Mawla 'Ali (A).
Thus through physical austerities and abstinence from pleasures and dietary luxuries, through obligatory or supererogatory fasting, he should remove the flesh that accumulated in his body through sin or during his sinful days. By means of spiritual exercises, worship and ritual devotions he must attend to the accretions of carnal nature. This is because the forms of physical pleasures still linger in the soul, and as these forms are present there the carnal self is inclined toward them and the heart is infatuated with them and it is feared that, God forbid, the self would rebel again and snatch away its reins.
Hence it is necessary for the wayfarers of the Hereafterly path and the penitent from sins to make the soul taste the pain of austerities and worship. If a night was spent in sin and licentiousness, that must be compensated with a night's watch devoted to the worship of God. If a day was spent in corporeal pleasures, that must be compensated with fasts and appropriate devotional rites. This is necessary so that the soul may be completely purged of the effects arid traces of the attachments arising from the love of the world. If this is done, tawbah, of course, becomes perfect arid the soul's primordial brilliance returns to it. Throughout the course of such exercises he must contemplate and meditate upon, the consequences of sin, the severity of God Almighty's might, the accuracy(exactness) of the Balance of deeds, and the intensity of the chastisement of Barzakh and Resurrection. He must understand and make his self and heart understand that all these things are consequences and forms of one's vicious deeds, of opposition to the King of kings. It is hoped that after this knowledge and reflection the soul will loath sins and detest them with a complete and total hatred, thus attaining the intended result of tawbah, which now becomes perfect and complete.
Those two stages thus are what make the station of tawbah perfect and complete. Of course, when man at first wishes to enter the station of tawbah, he must not think that he is required to reach the last of stages, so that the path appears to him to be full of difficulty and hardship and he decides to leave off once for all. To whatever extent the wayfarer of the path of Hereafter is able to traverse this path, it is good and desirable to that extent. After that, when he sets out on the path, God Almighty makes the journey easy for him. Hence the difficulty of the journey must not stop one from setting out towards his destination. For the goal is very great and important, and once one understands the greatness of the goal the hardships of the path become easy and bearable. Tell me, what goal is higher than eternal salvation, joy and bless? What peril is greater than eternal wretchedness and damnation? By shunning tawbah or postponing it and delaying it one may subject oneself to eternal wretchedness, unending punishment and everlasting damnation, and by performing it one may obtain absolute felicity and become the beloved of God. Hence if the goal is so great, why should one be scared of a few days' hardship?
You should know that whatever action one can take, even if little, is gainful. Compare the matters of the Hereafter with worldly affairs, wherein the worldly wise, if they are incapable of attaining their highest objective, do not desist from reaching a lower goal. If an objective cannot be obtained in its totality, that does not prevent them from attaining it partially. You too, if you are incapable of attaining this objective to its perfect degree, should not give up the principal goal itself. Try to achieve it to the extent that is possible for you.
The Result of Istighfar:
Of the things in respect of which it is necessary for the penitent person to act is taking refuge in the forgiveness of God Almighty and attainment of the state of istighfar. Openly and secretly, mournfully and pleadingly, in solitude, with lamentation, tears and wails of woe, he should implore the forgiveness of His Sacred Essence to cover his sins and wipe out their consequences. Of course, the forgivefulness and the veiling grace of that Sacred Essence implies the coating of defects and forgiveness of the sins' consequences. And since the spiritual forms of deeds are like a man's offspring, or something even more closely linked to him, and since the reality of tawbah and the form of istighfar is tantamount to disowning and cursing (li`an), God Almighty, since He is the All-forgiving and the Veiler, dissociates those offsprings of the penitent from him on account of his li'an and separates them from him.
Thereupon He obscures that sin from the sight(prospect) to all those beings that have come to know about his sin, including the angels and the notaries of offences, the time and the place of its commission, as well his own bodily members and organs, and makes them forget it, as pointed out in the noble tradition which says:
He makes His two angels forget that which they have recorded of his sins.
And possibly God Almighty's `inspiring' the bodily members and organs, as well as the earth's locations, to conceal(bury) the sins, as mentioned in the noble tradition, is the same as the erasing of the sins from their memory. It is also possible that it means a command to abstain from giving testimony. Or perhaps that which is meant is the obliteration of the effects of sins from bodily members, whose presence amounts to their existential witness, so that if one did not perform tawbah every one of his organs, either with the tongue of statement or condition, would bear testimony to his deeds.
As it is, God's station of forgivefulness and His veiling grace have required that now that we are in this world our organs and members abstain from giving testimony about our deeds and time and space conceal our actions. In the same way, if we leave this world with genuine tawbah and sincere istaghfar, they will conceal our deeds, or our deeds will be totally obscured for them. And perhaps the second explanation is more in order in view of the God Almighty's magnanimity, so that the penitent human being is not ashamed in front of anyone. And God knows best.
On the Interpretation of Tawbah Nasuh:
You should know that there is difference of opinion regarding the interpretation of the term tawbah nasuh and a concise(brief) mention of it is suitable here. Here we will confine ourselves to translating the words of the greater researcher al-Shaykh al-Bahai - may God sanctify his soul.
The informed traditionist al-Majlisi - may God have mercy upon him - quotes al-Shaykh al-Baha'i as having said that the exegetes have given several meanings of tawbatan nasuh. According to one of them, it means a tawbah that 'advise' the people, that is invites them to simulate him on account of the good effect produced in its performer, or that it `counsels' its performer to root out sins and to never return to their commission.
Another interpretation is that tawbah nasuh is a tawbah which is done purely (khalis) for God's sake, in the same way as pure honey free from wax is called `asal nasuh. And sincerity means that the remorse should be on account of the ugliness of sins or because they are contrary to God's good pleasure, not for the fear of hellfire.
The honourable researcher al-Tusi has ruled in the Tajrid that a remorse felt for sins on account of the fear of hellfire is not tawbah at all.
According to another interpretation, nasuh is related to nasabah, which means tailoring, because tawbah sews together the body of faith torn by sin, or because it joins the penitent person to God's awliya' and His lovers in the same way as separate pieces of cloth are joined together by tailoring.
According to yet another interpretation, `nasuh' here is an attribute of the penitent and is linked to tawbah in a metaphorical manner. That is, tawbah nasuh is a tawbah whose performer counsels and advises himself to perform it as perfectly and completely as it is worthy of being performed until the effects of sins are totally purged from the heart, which is attained by making the soul melt with regret and grief and by clearing the darkness of vices by the light of virtues.
All Beings are Endowed with Life and Knowledge:
Let it be known to you that there are certain realities, mysteries and subtleties for tawbah, and there is a specific tawbah particular to his own station for every one of the wayfarers of the path towards God. And since we do not partake of those stations, an elaboration of their details is not proper for these pages. Therefore it is better to conclude this discourse with the mention of a point inferable from the noble tradition, which is also in accordance with the literal meanings of the verses of the Noble Qur'an and a large number of traditions scattered(sprinkled) through various chapters. That point is that every one of the existents is possessed of knowledge, life and consciousness. Rather, all the existents possess the marifah (gnosis) of the station of God, the Glorious and the Sublime. The inspiration imparted to bodily organs and members and the earth's locations regarding the concealment (of sins) and their obedience to divine commands, the tasbih of all existents referred to expressly in the Glorious Qur'an and with the mention of which things the noble traditions are replete - all these are proof of their knowledge, cognition and life. Rather, they constitute the proof of a special relation between the Creator and the creation, of which none has any knowledge except the Sacred Essence of God Almighty and those who it pleases Him should know.
And this is itself one of the teachings that the Noble Qur'an and the traditions of the inerrant Imams have imparted to mankind, which is also in agreement with the views of the emanationist philosophers and the mystics, as well as the experience of the mystics. In the sublime science of metaphysics it has been proved that existence is identical with divine Excellences, Names and Attributes and at whatever level they manifest themselves and are reflected in a mirror, the manifestation is accompanied with all the aspects and excellences, including life, cognition and the rest of the seven main Attributes. And every one of the phases of manifestation of the reality of being and every level in the descendence of the light of the perfect beauty of the Deity has a special relation with the One, through which it has the secret gnosis of the Lord, as stated in the noble verse.
...There is no creature that crawls, but He takes it by the forelock. (11:56)
It is said that huwa (He) refers to the mystery of Divine Ipsiety, and `the taking by the forelock' is the same mysterious(uncannily), secret primordial existential relation the way to whose cognition is closed to all existents.
