allah does not have a son?
Allah has not taken any son, nor has there ever been with Him any deity. ... Exalted is Allah above what they describe [concerning Him]. — Quran, surah 23 (Al-Mumenoon), ayat 91. Say: He is Allah, the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him.
