Musannaf Ibn Abi Shaybah

Hazrat Umar bin Asid (may Allah have mercy on him) narrates that Hazrat Ibn Umar (may Allah be pleased with them both) said: Hazrat Ali bin Abi Talib (may Allah be pleased with him) was granted three distinctions. For me, attaining even one of them would be better than red camels. The Prophet (peace and blessings be upon him) gave his daughter to him in marriage, from whom his progeny continued, and the Prophet (peace and blessings be upon him) ordered all doors to be closed except his door. And on the day of the Battle of Khaybar, the Prophet (peace and blessings be upon him) granted him the flag.
