Surah Az-Zumar, Verse 4

لَّوۡ أَرَادَ ٱللَّهُ أَن يَتَّخِذَ وَلَدٗا لَّٱصۡطَفَىٰ مِمَّا يَخۡلُقُ مَا يَشَآءُۚ سُبۡحَٰنَهُۥۖ هُوَ ٱللَّهُ ٱلۡوَٰحِدُ ٱلۡقَهَّارُ٤

law arāda l-lahu an yattakhidha waladan la-iṣ'ṭafā mimmā yakhluqu mā yashāu sub'ḥānahu huwa l-lahu l-wāḥidu l-qahāru

If Allāh had intended to take a son, He could have chosen from what He creates whatever He willed. Exalted is He; He is Allāh, the One, the Prevailing.
