The Holy Quran 39:4 — Surah Az-Zumar
Arabic text
لَّوْ أَرَادَ ٱللَّهُ أَن يَتَّخِذَ وَلَدًا لَّٱصْطَفَىٰ مِمَّا يَخْلُقُ مَا يَشَآءُ ۚ سُبْحَـٰنَهُۥ ۖ هُوَ ٱللَّهُ ٱلْوَٰحِدُ ٱلْقَهَّارُ
Translation
If (one assumes that) Allaah intended (willed) to have a child, He would have chosen whatever He desires from His creation (and is not forced to take those whom the Mushrikeen name as His children). (However, the fact is that) He is Pure (from needing children), and He is the One, the Omnipotent.
