Surah 25

Surah 25:2

"– the One who – to Him (belongs) the kingdom of the heavens and the earth. He has not taken a son, nor has He any associate in the kingdom. He created everything and decreed it exactly."

25.2 – He has not taken a son, nor has He any associate in the kingdom
The warning against saying that “Allah has taken a son” appears many times in the Quran. Here this perceived confession is grouped with believing that Allah shares his sovereignty with a partner and with taking gods other than Allah (v. 3). See “Son of God in the Quran” and a summary of verses that accuse the People of the Book of “associating” at 61.9.
