Musannaf Ibn Abi Shayba 27:805

Abu Mu’awiyah narrated to us, from al-A’mash, from ‘Amr ibn Murrah, from Salim, from Hudhayfah, who said: "What Allah repels from the tents—it is not what He repels from the tents that were in Kufa—it is the tents that were with Muhammad, may Allah bless him and grant him peace."
