Surah Maryam — Ayah 35 (19:35)
مَا كَانَ لِلَّهِ أَن يَتَّخِذَ مِن وَلَدٖۖ سُبۡحَٰنَهُۥٓۚ إِذَا قَضَىٰٓ أَمۡرٗا فَإِنَّمَا يَقُولُ لَهُۥ كُن فَيَكُونُ ٣٥
English translation (Saheeh International)
It is not [befitting] for Allāh to take a son; exalted is He!1 When He decrees an affair, He only says to it, "Be," and it is.
- - i.e., far removed is He from any such need.
Brief commentary
It does not befit Allah to have a son, exalted and free He is from this. When He intends something, it is enough for Him to say regarding this thing: Be, and it most definitely becomes. So He who is like this is free from having a son.
