Of things that cause fear of God, is contemplation of the extremeness of Divine Might, the precision(exactness) and sharpness of the path (sirat) of the Hereafter and the perils that man has to face during the days of his life and at death, as well as the hardships of the Purgatory (barzakh) and the Resurrection and the scrutinies of the Reckoning (hisab) and the Balance (mizan). In the same way, reflection over the verses and traditions about the promises of God Almighty can bring about complete and perfect hope. It is reported in traditions that on the Day of Resurrection God Almighty's mercy shall be so abundant(lavish) that even Satan will aspire for God's pardon. In this world, at which God has never looked with favour, and on which since its creation His mercy has not descended (in comparison to the other worlds) except for a droplet of it, we encounter so much of the abundance of God's mercy, bounty and care, which has enveloped everything, apparent and the invisible, that the world is a vast table of the bounties and gifts of the Almighty, so widespread that were all the world's intellects attempt to encompass even a fragment of it, they would be unable to do so. If this is so, then what would be a world which is the house of the hospitality of the generous Lord and the abode of the expansive mercy and compassion of the All-merciful and the Compassionate? Of course, .Satan would be justified in his aspiring for His pity and his hoping from God's generosity. Hence, make perfect your good opinion of Him and rely upon His grace, as He has declared:
Verily, God shall forgive all the sins. (39:53)
and immerse all in the ocean of His mercy and beneficence. It is impossible that God should break His promise, although it is possible that He may withdraw His threats(menaces), and how often He does that! So gladden your heart with the hope of His mercy, for had it not enveloped you, you would not be a creature; every creature is the recipient of His mercy, for He has said:
...My mercy embraces all things. (7:156)
The Difference Between Hope and Delusion:
However, my dear, you should be careful of distinguishing between hope and delusion, for it may be that you be a deluded man, but imagine yourself to be a man of hope. Yet it is easy to distinguish between them on the basis of their grounds. You should reflect over the state of yours that makes you regard it as hope, to see whether that state of yours has come into being as a result of your belittling of Divine commands or as a result of conviction in the all-embracing character of Divine mercy and the greatness of the Holy Essence. Should that prove to be difficult, the distinction can be made on the basis of their effects. Should the greatness of God be imprinted on the believer's heart and should it be content in the expansive mercy and bounty of His Holy Essence, he would be committed to His obedience and service, for esteem for someone great and gratitude and willingness to serve one's benefactor are inviolable features of human nature. Hence, should you be committed to the duties of slavehood and unsparing in your efforts to obey and worship; should you not rely on your works and consider them insignificant; should your hope rest on God's mercy, grace and bounty; should you consider yourself entitled to every kind of blame, disfavour, reproof and wrath on account of your deeds; and should your sole reliance be the mercy and generosity of the Absolutely Magnanimous - should you be such, then you are indeed in possession of the state of hope. Then, thank God Almighty for that, and implore His Holy Essence to establish it firmly in your heart and to elevate you to a higher degree of it. But if, God forbid, should you be one who belittles and takes lightly the commands of God, one who considers unimportant and insignificant the Words of the Holiest Essence, then rest assured that it is delusion that has appeared in your heart as a result of the guiles of Satan and your carnal self. Had you any faith in God's greatness and His expansive mercy, its effects would have been obvious in you. A claimant whose acts are contrary to his claims is one who falsifies himself, and there are many traditions to this effect.
In al-Kafi, al-Kulayni, with his chain of narrators, reports from al-'Imam al Sadiq (A) on the authority of an unnamed narrator who narrated it to Ibn Abi Najran, that he said to the Imam (A): "There are some people who commit sins and say we are hopeful. They remain in this condition until death comes to them." The Imam said: "They are a people who have been swept away by false hopes. They lie, they are not the hopeful; for verily, one who has hope of something pursues it, and one who fears something flees from it."
Close to this in meaning is another tradition of the noble al-Kafi:
(Al-Kulayni), with his chain of narrators reports from al-Husayn ibn Abi Sarah that he said: "I heard Abu 'Abd Allah (A) say: `A believer is not but fearful and hopeful, and he is not (truly) fearful and hopeful unless he responds in action in regard to that which he fears and hopes.' "
Some have said that the person who is hopeful without doing anything is like the one who awaits the result without preparing its needed means, like the farmer(peasant) who awaits a ready harvest without sowing the seeds, without tilling and watering his land(landscape) and without removing the hindrances in the way of a sufficient produce. Such a man cannot be said to have hope. What characterizes him is stupidity and folly. The similitude of the person who does not reform his morals and acts without refraining from sins, is the farmer who sows his seeds in barren, saline soil: of course, such farming(farmstead) does not yield any produce.
Therefore, the genuine kind of hope is that man should first prepare all the means that are available to him and have been provided to him by the grace of God Almighty, Who has also guided him regarding the paths of right and corrupt conduct and commanded him to make ready those means, and only then he should wait and hope that God, with His favour, will provide the remaining means over which he has no power, and remove the hindrances and perils from his path. Hence, when the devotee has cleared the field of his heart of the thorns of moral vices and of the stones, rocks and salinity of sins, sowing therein the seeds of good works and watering it with the clear waters of lucrative knowledge and sincere faith and guarded his field against the pests of pride (`ujb) and ostentation (riya'), which like weeds hinder the wholesome growth of the harvest, then he may sit and wait for God's grace, hoping that the Almighty may keep him firm(taut) and on the straight path until the last moment of his life. This is the desired and genuine kind of hope, as declared by God Almighty:
But the believers, and those who migrate and struggle in the way of God -those have hope of God's compassion; and God is All-forgiving, All-compassionate. (2:213)
The noble tradition at its end mentions that neither fear(nervousness) nor hope should exceed one another, and the same thing is stated in the mursal hadith of Ibn Abi `Umayr from al-'Imam al-Sadiq (A). When man observes his extreme shortcoming in fulfilling the demands of servitude and creaturehood and when he contemplates the narrowness of the path of the Hereafter, a high degree of fear seizes him. And when he observes his own sins and reflects over the condition of those persons who were righteous at the start but fell into wretchedness and departed from the world in a state of unbelief and without good works, ultimately meeting an evil goal, his fear is intensified. And in a noble tradition of al-Kafi, al-'Imam al-Sadiq (A) is reported to have said:
...The believer stands between two dreadful things: the past sins, regarding which he does not know what God will do (with him), and the remainder of his life, regarding which he does not know what mortal sins he will commit therein. So he does not wake up except in a state of dread, and nothing keeps him righteous except fear. [7]
The same thing is stated in the sermon of the Noble Messenger (S) reported in a hadith of al-'Imam al-Sadiq (A) in al-Kafi. [8] The gist of the matter is that the self is in a state of utter imperfection and shortcoming, and God at the height of greatness, glory, all-embracing mercifulness and grace, and the devotee is always in a median state of fear and hope between these two views. And since the Divine attributes of glory and perfection cast their light simultaneously on the wayfarer's heart, none of the two, fear or hope, exceeds the other.
Some have said that sometimes fear is more beneficial for man -as in the state of health and robustness - in order that he may endeavour in attaining perfection and performing good works, and that hope is better in some conditions - as when the signs of approaching death appear - so that man may meet God in a state which He loves more. But this opinion does not agree with the above discussion and the traditions mentioned, for the genuine and lovable hope also induces one to good works and hereafterly conduct. Fear of God is also always desirable and is not contrary to confirmed hope in Him.
And some have said that fear is not a moral or intellectual merit in the Hereafter, and that its benefit is limited to the world, which is the abode of works and; deeds, for inducing obedience and service and for restraining men from sin. It is of no use after this world is left behind. On the other hand, hope rill never end and shall endure(withstand) in the Hereafter, for the more of God's beneficence man receives, the more does he aspire to 'His grace and bounty, because the stores of God's mercy axe inexhaustible. Hence, fear comes to an end, while hope continues.
The Opinion of Al-Majlisi:
The great muhaddith al-'Allamah al-Majlisi, upon whom be God's mercy, says: "The truth is that as long as the devotee is in the abode of duty (i.e. this world), he is bound to have both fear and hope. However, after his witnessing of the matters of the Hereafter, one of them, of necessity(urgency) , must surpass the other."
This writer says: That which has been said regarding the dominance of fear or hope in the Hereafter does not agree with the above discussion about the meaning of hope and fear. Even if supposedly true, it would apply only to those of middle stations, for the state of the elect and the awliya' is different from that; for their witnessing of the Divine majesty and glory and the irradiations (tajilliyat) of the Names of love and beauty, which are attained in the heart, are not effaced by the witnessing of the matters of the Hereafter; as a result their fear and hope do not surpass each other. Rather, the effects of Divine majesty and glory and the irradiations of His beauty and love are greater in the world of the Hereafter, and the awe resulting from God's majesty is one of the spiritual pleasures, which on reflection will not be found to be contrary to the noble verse:
Surely God's friends - no fear shall be on them, neither shall they sorrow. (10:62)
And that which has been said regarding fear, that it is not a spiritual merit -- it is not true of the awe in front of God's greatness and glory, for it is an excellence and is more intense in those of perfect and complete character (kamilun, mukammalun) than others. And praise belongs to Allah, for His majesty and His beauty, and may His benedictions be upon Muhammad and his Family.
