‘Uthman reported God’s messenger as saying, “ One who is on pilgrimage may not marry, or give someone in marriage, or make a betrothal.” Muslim transmitted it.
وَعَنْ عُثْمَانَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يَنْكِحُ الْمُحْرِمُ وَلَا يُنكِحُ وَلَا يَخْطُبُ» . رَوَاهُ مُسلم
