Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) performed four Umrahs: the Umrah of al-Hudaybiyah, the Umrah of al-Qada' the following year, the Umrah from al-Ji'ranah, and the fourth Umrah with his Hajj.
Abu al-Hasan (Ali bin Abd al-Aziz) said: No one says "from Ibn Abbas" in this hadith except Dawud bin Abd al-Rahman. The Shaykh said: Sufyan bin Uyaynah narrated it from Amr bin Dinar from Ikrimah (may Allah have mercy on him), that the Prophet (peace and blessings be upon him) performed Umrah, but this report is mursal. Imam al-Bukhari (may Allah have mercy on him) said: Dawud bin Abd al-Rahman is saduq (truthful), except that he sometimes errs in something.
