Ubaydullah ibn Mu'adh al-'Anbari narrated to us: My father narrated to us: Shu'bah narrated to us, from 'Adi — and he is Ibn Thabit — who said: I heard Abdullah ibn Yazid narrating from Zayd ibn Thabit that the Prophet (peace be upon him) set out toward Uhud, and some of those who were with him turned back. The companions of the Prophet (peace be upon him) were divided into two groups concerning them. Some of them said, "We will kill them," and others said, "No." Then the verse was revealed: "What is the matter with you that you are divided into two groups concerning the hypocrites?"
