If Allah had intended to take a son, He could have chosen from what He creates whatever He willed. Exalted is He; He is Allah , the One, the Prevailing.
Tafseer
{ لو أراد الله أن يتخذ ولدا } كما قالوا: (اتخذ الرحمن ولدا) { لاصطفى مما يخلق ما يشاء } واتخذه ولدا غير من قالوا الملائكة بنات الله وعزير ابن الله والمسيح ابن الله { سبحانه } تنزيها له عن اتخاذ الولد { هو الله الواحد القهار } لخلقه .
{If God had willed to take a son} as they said: {The Most Gracious has taken a son} {He would have chosen from what He creates whatever He willed} and He took him as a son other than those they said: The angels are daughters of God, Ezra is the son of God, and the Messiah is the son of God. {Glory be to Him}, sanctifying Him from taking a son. {He is God, the One, the Prevailing} of His creation.
