فتح مكة
At the Conquest of Mecca, Muhammad placed Sa'd in command of one branch of the army. Sa'd led them off declaring: "Today is a day of war. Sanctuary is no more!" Umar heard him and told Muhammad that he was afraid that Sa'd would resort to violence. Muhammad therefore ordered Ali to run after Sa'd and take the flag from him and carry it in himself. An alternative tradition states that Sa'd had to give the flag to his son Qays.
