The Prophet ﷺ said, "Whatever I have told you comes from Allah, that is what admits no doubt."
عن النبي ﷺ قال: ما أخبرتكم أنه من عند الله فهو الذي لا شك فيه.
Bazzar (8900) narrated it from Ahmad bin Mansur (that is, Ramadi), who said, Abdullah bin Salih told us, Layth (that is, Ibn Saad) told us, from Ibn Ajlan, from Zayd bin Aslam, from Abu Salih (that is, Samman), from Abu Hurairah, and he related it.In its chain is Abdullah bin Salih, the scribe of Layth, and there is weakness in him, though he has been corroborated. Ibn Hibban said, following (2106), Ibn Ajlan said, Zayd bin Aslam told me, and he related it with its chain and wording. It appears this is connected to the chain before it, which is, Umar bin Muhammad Hamdani told us, Abdul-Malik bin Shuayb bin Layth bin Saad told us, my father told me, from my grandfather, from Muhammad bin Ajlan.This chain is hasan because of Muhammad bin Ajlan.
