Musannaf Ibn Abi Shaybah 39851 — Reports on the caliphate of Umar bin

It is narrated from Amr bin Maymun, who said: I used to leave the first row out of awe of Sayyiduna Umar (may Allah be pleased with him). On the day Sayyiduna Umar was attacked, I was in the second row. Sayyiduna Umar came and said: "O servants of Allah! The prayer; straighten (your rows)." The narrator said: He began leading us in prayer when Abu Lu'lu'ah struck him two or three blows. The narrator said: Sayyiduna Umar was wearing a yellow garment. The narrator said: He gathered this garment to his chest, then he fell down, saying: "And the command of Allah is a decree determined" [Al-Ahzab: 38]. Then he (the attacker) killed and struck twelve or thirteen more people. The narrator said: The people rushed towards the killer, and he leaned on his dagger and killed himself.
