Allâh's Messenger (ﷺ) said, "(The performance of) ' Umra is an expiation for the sins committed between it and the previous one. And the reward of Al-Hajj-Al-Mabrûr (the one accepted by Allâh) is nothing but Paradise." [3:1-O.B]

that he was asked about the ' Umra before Hajj. (Ibn 'Umar) replied, "There is no harm in it." ('Ikrima said) Ibn 'Umar also said, "The Prophet (ﷺ) had performed 'Umra before performing Hajj. [3:2-O.B]

How many times the Prophet (ﷺ) had performed Umra. He replied, "Four times; one of them was in the month of Rajab." The questioner asked 'Aisha, "O Mother ! Don't you hear what ' Abdur is saying?" She said, "What does he say?" " Urwa said, "He says that Allâh's Messenger (ﷺ) performed four ' Umra and one of them was in the month of Rajab." Aisha said, May Allâh be Merciful to Abdur-! The Prophet (ﷺ) did not perform any ' Umra except that he was with him, and he never performed any ' Umra in Rajab. [3:4-0.B]

I asked Anas How many times the Prophet (ﷺ) had performed Umra? He replied, "Four times: 1. ' Umra of Hudaibiya in Dhil-Qa'da when the pagans hindered him; 2. ' Umra in the following year in Dhil-Qa'da after the peace treaty with them (the pagans); 3. ' Umra from Al-Ji'râna where he distributed the war booty." I think he meant the booty (of the battle) of Hunain. [4. ' Umra along with his Hajjat-ul-Widâ]. I asked, "How many times did he perform Hajj? He (Anas) replied, "Once." [3:6-O.B]

I Asked Anas (about the Prophet's Umra) and he replied, "The Prophet (ﷺ) performed Umra when the pagans made him return and ' Umra of Al-Hudaibiya (the next year), and another 'Umra in Dhil-Qa‘da, and another 'Umra in combination with his Hajj. [3:7-0.B]
