Imam Ibn Sirin, may Allah have mercy on him, said: I entered the mosque (and saw) that Aswad bin Sari’ was narrating stories, and Humaid bin Abdur Rahman was engaged in scholarly discussion in a corner of the mosque. I was hesitant about which gathering to join. I became drowsy, and someone came and said: Are you hesitant about where to sit? If you wish, I can show you the place where Jibreel (peace be upon him) sits in the gathering of Humaid bin Abdur Rahman.
