Hajj is the fifth pillar of Islam. The Messenger of Allah (may Allah's peace and blessings be upon him) clarified the rituals of Hajj in his words and deeds, which were reported by the noble Companions (may Allah be pleased with them) just as they had learned them from the Prophet (may Allah's peace and blessings be upon him). During Hajj, some of what is permissible becomes forbidden for the one who assumes Ihrām. In this Hadīth, the Tābi‘i Yazīd ibn al-Asamm reports that his maternal aunt, Maymūnah bint al-Hārith (may Allah be pleased with her), wife of the Prophet (may Allah's peace and blessings be upon him), reported that the Messenger of Allah (may Allah's peace and blessings be upon him) married her when he was Halāl, i.e., was not a Muhrim (one in the state of Ihrām). In Abu Dāwūd's narration, Maymūnah (may Allah be pleased with her) said: "The Messenger of Allah (may Allah's peace and blessings be upon him) married me when we were both Halāl (outside the state of Ihrām) at Sarif." The Prophet (may Allah's peace and blessings be upon him) contracted marriage with her on his way to Makkah to make ‘Umrah al-Qadā’ (deferred ‘Umrah) in 7 AH, before assuming Ihrām. Their marriage became known after he had assumed Ihrām. Then, he consummated marriage with her when he was outside the state of Ihrām on the way back to Madīnah in an area called Sarif, which is almost 10 kilometers away from Makkah, and it was said: 16 kilometers away, and there are other opinions as well. Then, Yazīd reported that Maymūnah (may Allah be pleased with her) was his maternal aunt and the maternal aunt of Ibn ‘Abbās (may Allah be pleased with him and his father) in reference to Ibn ‘Abbas's mistake in what he reported about the Prophet's marrying Maymūnah while being a Muhrim. However, Maymūnah (may Allah be pleased with her) certainly knew herself better than Ibn ‘Abbās. Moreover, the Prophet (may Allah's peace and blessings be upon him) said: "The Muhrim (one in the state of Ihrām) must neither marry, nor give someone in marriage, nor get engaged."
