Da'ud bin 'Abdur Rahman al-'Atar داود بن عبد الرحمن العطار · The Book on Hajj

"I said to Anas bin Malik: 'How many times did the Prophet perform Hajj?' He said: 'He performed one Hajj and he performed four Umrah: An Umrah during Dhul-Qa'dah; the Umrah of Al-Hudaibiyah, and Umrah with his Hajj, and an Umrah from Al-Ji'irranah when he divided up the war spoils of Hunain.'"
