The polytheists said to the Prophet ﷺ, "Muhammad, describe to us the lineage of your Lord."So Allah revealed, "Say, He is Allah, the One. Allah, the Eternal Refuge. He neither begets nor is born, nor is there to Him any equivalent." [Ikhlas 112:1–4]
حدثنا أبو سعد محمد بن ميسر الصاغاني حدثنا أبو جعفر الرازي عن الربيع بن أنس عن أبي العالية

Its chain of transmission is daif, because of Muhammad bin Maysarah Abu Saeed Saghani, whose weakness they unanimously agree on. Tirmidhi narrated it through his route, 5/451, number 2364, without commenting on it, only indicating that it was outweighed by a stronger version. It was graded sahih in al-Mustadrak through the route of Muhammad bin Sabiq from Abu Jafar Razi, and Dhahabi agreed with him, 2/54, and it is found in Tabarani's tafsir, 30/221.
