All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad
is His slave and Messenger.
This answer is correct. Its essence is that Allah, the Exalted, by virtue of His perfect self-sufficiency, has no need of a wife or a child.
To believe that Allah has a child necessarily entails attributing to Him deficiency, need, and want; for a person seeks to have a child out of his need for the child's help, support, and companionship, whereas Allah, Glorified and Majestic, is self-sufficient and transcendent above all of that. For this reason, Allah, the Glorified, praised Himself for not taking a child, on account of the perfection of His self-sufficiency, His sovereignty, and the servitude of all things to Him. Allah, the Exalted, says (what means): {They say, 'Allah has taken a son.' Exalted is He! He is the Self-Sufficient. To Him belongs whatever is in the heavens and whatever is on the earth. You have no proof for this. Do you say about Allah that which you do not know?} [Quran 10:68]
Allah, the Glorified, has further demonstrated the rational impossibility of this corrupt belief in Sūrat Al-Ikhlāṣ, which is equivalent to one-third of the Qur'an: {Say: He is Allah, the One. Allah, the Self-Sufficient Master. He neither begets nor is born. Nor is there to Him any equivalent} [Quran 112:1– 4]
There is no doubt that the belief that Allah has a child is among the most heinous forms of disbelief, the gravest misguidance, and the most repugnant falsehood. Allah, the Exalted, says in refutation of this corrupt belief (which means): {And they say, 'The Most Merciful has taken a son.' You have certainly done a heinous thing. The heavens almost rupture therefrom, and the earth splits open, and the mountains collapse in devastation, that they have attributed to the Most Merciful a son. And it is not appropriate for the Most Merciful that He should have a son. There is no one in the heavens and earth except that he comes to the Most Merciful as a servant} [Quran 19:88 – 93]
Allah Knows best
