That the belief in the unity of the Divine Essence is innate and so is the belief that the Divine Being encompasses all the attributes of perfection became known in the above section; here we shall prove this in a different manner.
It should be known to you that one of the characteristics of the nature upon which God has fashioned mankind is a loathing for imperfection. Man is by nature averse to everything he perceives as defective and faulty.
Thus imperfection and defectiveness are repulsive to human nature, for it is inclined towards absolute perfection. Now, the pole of attraction of human nature should be one and unique, because everything capable of plurality and everything made up of parts is imperfect and defective. Plurality is always associate with finitude, (which is a defect), and everything that is defective is repelled by human nature, which is not attracted towards it. The presence of these two natures-that is, the nature of attraction towards perfection and the nature of repulsion towards defectiveness-not only posits the principle of tawhid, it also pits that the Being of God encompasses every perfection and that It is free from every defect. The blessed Surat al-Tawhid, which is about the Being of God, the Exalted and the Supreme, relates, in the words of our revered Shaykh--may my soul be his ransom-to the Ipseity of the Absolute, which is the pole of attraction of the human nature. At the outset of the surah, it is referred to as huwa (He), followed by the six attributes mentioned in the following verses. Since His sacred Essence has an absolute ipseity (huwiyyah) (an absolute ipseity must be absolutely perfect; otherwise it is a finite ipseity), the Divine Being encompasses all perfections. `Allah', (which follows the pronoun huwa in the surah), shows that in spite of encompassing all perfections, It is simple (basit); otherwise It would not have an absolute ipseity . Thus, He is ahad (unique) and His ahadiyyah (uniqueness) necessitates His wahidiyyah (oneness). And since absolute ipseity includes all perfections and is free from all defects-which originate in finite ipseity He is Samad (Eternal, the End, Goal and Refuge of every thing) and is not vacuous. On account of His being absolute ipseity, nothing is begotten or separated from Him, nor is He Himself separated from anything. He is lam yalid wa lam yulad, i.e. He begetteth not, nor was begotten; rather, He is the Source of everything and the End to which all existents return without having separated from Him, for separation necessitates defectiveness. Absolute Ipseity has no equal either, since absolute perfection precludes recurrence. Thus, the blessed Surat al-Tawhid is about the laws of human nature and is concerned with the attributes of the Divine Being.
3. Innateness of-the Belief in Resurrection:
Here we shall discuss the innateness of the belief in Resurrection (al-ma'ad) as something ingrained in human nature. Like the other beliefs dealt with in the previous sections, it can be proved in a number of ways. Here we shall mention only some of them.
Know that one of the God-given innate tendencies that are ingrained in the nature of the entire human species is the love of comfort. If all the epochs of human existence--from civilized existence to barbarian subsistence, from eras of piety to that of pagan rebellion-are studied and if all the different kinds of individuals-from the learned to the ignorant, from the noble to the mean, and from the savage to the urbanized-are questioned as to the aim of all their various attachments and pursuits and their diverse desires, and if they are asked about the purpose of their hardships and labours, all will unanimously answer in one voice with the unambiguous tongue of nature that whatever we desire is for the sake of our comfort. They will say that the ultimate goal and the purpose underlying all their aspirations and hopes is absolute comfort, untainted with labour, toil and distress. Since such a toilless, painless comfort is the goal of all, everyone imagines that lost comfort to lie in some thing and develops an interest in every such thing which he believes to be associated with that desired goal. This, in spite of the fact that such an absolute comfort is not to be found in any part of this world of ephemeral existence, nor is such an undisturbed peace and rest possible here. All the bounties and blessings of this world are mixed with tiresome effort and exhausting toil. All the pleasures of the world are surrounded with unnerving pains. Pain and agony, anguish and sorrow, anxiety ,worry and grief prevail all over the world. Throughout the entire history of human existence, not a single individual is to be seen whose pains and sufferings are equal to his comforts and whose joys and blessings are equal to his sorrows, distresses and toils, let alone the possession of untainted reassurance and undisturbed rest.
Accordingly, the ultimate human goal is not to be found in this world, and no natural, inherent and actual love-and that too a love which pervades the entire species-is possible without the existence of an actual beloved. Hence, there should exist such a world in the realm of existence where comforts will not be adulterated with labour and pain, whose ease and repose be absolute and pure, unmixed by pain, whose joys should be pure, unmarred by grief and suffering. That world is the House of Divine bounty (dar al-na`im), the world of the manifestation of His magnanimity.
That world can also be posited by means of the freedom-loving nature of man and the insistence of the human will, which are ingrained in the nature of every human individual. Since the material forces of this world and the conditions therein, with its impediments and restrictions, are opposed to human freedom and contrary to the human will, there should be a world in the realm of existence where man's will can be influential and whose material forces are not opposed to the dictates of the human will. Man would be there a free actor, accomplishing the aspirations of his sovereign will, a sovereignty which is demanded by his nature. Thus the aspects of the innate love of comfort and love of freedom are two natural tendencies that have been embedded by God in the unchanging nature of the human being. They are the two wings with which man flies towards the higher kingdom of heaven and into the Nearness of God.
There are certain other matters which are not of immediate relevance to these pages. There are other natural tendencies in man which posit other Divine teachings, such as the affirmation of prophethood, the raising of Divine apostles and the descent of the scriptures, and so on. Each of the above-mentioned natural tendencies proves all the sacred doctrines, but we have cramped our discussion in order not to digress much from the main topic, which is exposition of the glorious tradition at hand. Hitherto our discussion showed that the knowledge of the Source, Its Perfection and Unity, and that of the Hereafter is innate in human nature. And all praise is God's.
