Al-Husayn b. Ahmad b. Idris (ra) narrated to us. He said: My father narrated to us. He said: Ahmad b. Muhammad b. Khalid narrated to us from his father from Khalaf b. Hammad from Abi’l Hasan al-`Abdi from Sulayman b. Mehran from Abi Ishaq from `Amr b. Habashi from al-Hasan b. `Ali b. Abi Talib (as). He said
No banner proceeded to battle against Amir al-Mu’minin (as) except that Allah defeated it [through him] and made him triumphant over its companions and made them turn back in shame. None struck by Amir al-Mu’minin’s sword, the dhulfiqar, prevailed. When he would fight, Gabriel would fight on his right side, Michael would be on his left side, and the Angel of Death would be in front of him.
