Nubaih b. Wahb reported that 'Umar b. Ubaidullah intended to marry Talha b. 'Umar with the daughter of Shaiba b. Jubair; so he sent a messenger to Aban b. Uthman to attend the marriage, and he was at that time the Amir of Hajj. Aban said: I heard 'Uthman b. 'Affan say that Allah's Messenger (ﷺ) had stated: A Muhrim must neither marry himself, nor arrange the marriage of another one, nor should he make the proposal of marriage.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنْ نُبَيْهِ بْنِ وَهْبٍ، أَنَّ عُمَرَ بْنَ عُبَيْدِ اللَّهِ أَرَادَ أَنْ يُزَوِّجَ طَلْحَةَ بْنَ عُمَرَ بِنْتَ شَيْبَةَ بْنِ جُبَيْرٍ : فَأَرْسَلَ إِلَى أَبَانَ بْنِ عُثْمَانَ يَحْضُرُ ذَلِكَ ، وَهُوَ أَمِيرُ الْحَجِّ ، فَقَالَ أَبَانٌ سَمِعْتُ عُثْمَانَ بْنَ عَفَّانَ يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَنْكِحُ الْمُحْرِمُ وَلاَ يُنْكَحُ وَلاَ يَخْطُبُ " .
