Explanation

This Hadīth, which is reported by Ibn ‘Abbās (may Allah be pleased with him), shows that the Prophet (may Allah's peace and blessings be upon him) concluded his marriage contract with the Mother of the Believers Maymūnah during the state of Ihrām and consummated marriage with her after he terminated his Ihrām. Maymūnah (may Allah be pleased with her) died in a place between Makkah and Madīnah called Sarif, which is the place where the Prophet (may Allah's peace and blessings be upon him) consummated marriage with her. The scholars mentioned that Ibn ‘Abbās (may Allah be pleased with him) was inaccurate in saying that the Prophet (may Allah's peace and blessings be upon him) married Maymūnah during the state of Ihrām, being the only narrator of this incident. Most of the Companions disagreed with him, including Maymūnah and Abu Rāfi‘ who knew the story better than Ibn ‘Abbās. Abu Rāfi‘ (may Allah be pleased with him) said: "I was a messenger between the Prophet (may Allah's peace and blessings be upon him) and Maymūnah. He married her when he was outside the state of Ihrām and consummated marriage with her when he was outside state of Ihrām." Also, Mother of the Believers Maymūnah (may Allah be pleased with her) used to say: "He married me when he was outside the state of Ihrām: "So it is possible that Ibn ‘Abbās (may Allah be pleased with him) did not learn of the Prophet's marriage with Maymūnah except after the Prophet had entered the state of Ihrām. So he thought that the Prophet (may Allah's peace and blessings be upon him) married her during Ihrām. Commenting on this Hadīth of Ibn ‘Abbās, some scholars said that the Prophet (may Allah's peace and blessings be upon him) married Maymūnah in the Precincts of Makkah while he was not in the state of Ihrām.
