1543 — And Abū Bakr ibn Abī Dāwūd narrated to us, saying: al-Musayyab ibn Wādih ⦗2064⦘ al-Sulamī narrated to us, saying: Marwān ibn Mu'āwiyah narrated to us, from Qanān ibn Abd Allah al-Nahmī, who said: Mus'ab ibn Sa'd ibn Abī Waqqās narrated to us, from his father, who said: I was in the mosque with two men, and they spoke disparagingly of Ali—may Allah be pleased with him. The Messenger of Allah—may Allah’s blessings and peace be upon him—then approached angrily, and I could see the anger on his face. I said, “I seek refuge in Allah from the anger of the Messenger of Allah—may Allah’s blessings and peace be upon him.” He said: “What is wrong with you? Whoever harms Ali has harmed me. Whoever harms Ali has harmed me. Whoever harms Ali has harmed me.”
