(36:36) Holy is He Who created all things in pairs, whether it be of what the earth produces, and of themselves, and of what they do not know.
Glory be to Him: He is free from every defect and fault, from every error and weakness, and that another one should be His associate and partner in His work. The Quran has generally used these words when refuting polytheistic beliefs, because every belief of shirk is, in fact, an imputation of some defect, some weakness and some fault to Allah. When a person says that Allah has an associate, he in fact, thinks that either Allah is incapable of running and ruling His Kingdom alone, or He is under compulsion to make another His associate in His work. Or, some other beings are so powerful in themselves that they are interfering in God’s administration and God is putting up with their interference. Or, God forbid, Allah has the weaknesses of the worldly kings, due to which He is surrounded by an army of ministers, courtiers, flatterers and beloved princes or princesses, and thus many powers of Godhead have become divided among them. Had there been no such notions of ignorance about Allah in the minds, there could be no question of any idea of shirk in the world. That is why it has been stated again and again in the Quran That Allah is free from and exalted far above those defects and faults and weaknesses which the mushriks ascribe to Him.
31. This is still another argument for Tauhid. Here again certain realities of daily experience have been mentioned and it is suggested that man observes these day and night but does not ponder over them seriously, whereas they contain signs and pointers to the reality. The coming together of the man and woman is the cause of man’s own birth. Procreation among the animals also is due to the combination between the male and the female. Also about vegetation, man knows that the law of sex is working in it. Even among the lifeless substances when different things combine with one another, a variety of compounds come into existence. The basic composition of matter itself has become possible due to the close affinity between the positive and the negative electric charges (what about the charge-less neutrons here). This law of the pairs which is the basis of the existence of the entire universe (again false), contains in itself such complexities and finenesses of wisdom and workmanship, and there exist such harmonies and mutual relationships between the members of each pair that an objective observer can neither regard it as the result of an accident, nor can he believe that many different gods might have created these countless pairs and matched their members, one with the other, with such great wisdom. The members of each pair being a perfect match for each other and coming into being of new things with their combination itself is an explicit argument of the Creator’s being One and only One.
