Qatadah (may Allah have mercy on him) said: I asked Sayyiduna Anas bin Malik (may Allah be pleased with him): How many Hajjs did the Prophet (peace and blessings be upon him) perform? He said: He performed one Hajj and four Umrahs: one Umrah from which the polytheists turned him back, the second Umrah in the following year after the peace treaty, the third Umrah from al-Ji'ranah when he distributed the spoils of Hunayn in Dhu al-Qa'dah, and the fourth Umrah along with his Hajj.
