6584. Abū Ḥāzim added: An-Nu'mān bin Abī 'Ayyāsh, on hearing me, said, "Did you hear this from Saḥl?" I said: Yes." He said, "I bear witness that I heard Abū Sa'īd Al-Khudrī saying the same, adding that the Prophet ﷺ said, 'I will say: They are of me (i.e., my followers). It will be said: You do not know what they innovated (new things) in the religion after you left. I will say: Far removed, far removed (from mercy), those who changed (their religion) after me."
