I asked Anas, "How many times did the Messenger of Allah ﷺ perform Hajj?"He replied, "One Hajj, and he performed Umrah four times."
سألت أنسا: كم حج رسول الله ﷺ؟ قال: حجة واحدة، واعتمر أربع عمر.
Bukhari narrated it in Umrah (1778), and Muslim in Hajj (1253), both of them through Hammam, from Qatada, who mentioned it, and the wording is Muslim's.
