Umar b. Ubaidullah b. Ma'mar sent me to Aban b. Uthman as he wanted to make the proposal of the marriage of his son with the daughter of Shaiba b. Uthman. He (Aban b. Uthman) was at that time (busy) in the season of Pilgrimage. He said: I deem him to be a man of the desert (for it is a common thing) that a Muhrim can neither marry, nor is he allowed to be married to anyone. It is Uthman (b. Affan) who reported this to us from Messenger of Allah ﷺ.
حَدَّثَنِي نُبَيْهُ بْنُ وَهْبٍ قَالَ بَعَثَنِي عُمَرُ بْنُ عُبَيْدِ اللَّهِ بْنِ مَعْمَرٍ وَكَانَ يَخْطُبُ بِنْتَ شَيْبَةَ بْنِ عُثْمَانَ عَلَى ابْنِهِ فَأَرْسَلَنِي إِلَى أَبَانِ بْنِ عُثْمَانَ وَهُوَ عَلَى الْمَوْسِمِ فَقَالَ أَلاَ أُرَاهُ أَعْرَابِيًّا إِنَّ الْمُحْرِمَ لاَ يَنْكِحُ وَلاَ يُنْكَحُ أَخْبَرَنَا بِذَلِكَ عُثْمَانُ عَنْ رَسُولِ اللَّهِ ﷺ
