Nubaih bin Wahb narrated that the eye of ʿUmar bin Ubaidullah became inflamed when he was in ihram, and he wanted to apply kohl to it, but Aban bin ʿUthman ؓ forbade him to do that and told him to apply aloes to it. He said that ʿUthman ؓ narrated from the Messenger of Allah ﷺ that he had done that.
حَدَّثَنِي نُبَيْهُ بْنُ وَهْبٍأَنَّ عُمَرَ بْنَ عُبَيْدِ اللهِ بْنِ مَعْمَرٍ رَمِدَتْ عَيْنُهُ وَهُوَ مُحْرِمٌ فَأَرَادَ أَنْ يُكَحِّلَهَا فَنَهَاهُ أَبَانُ بْنُ عُثْمَانَ وَأَمَرَهُ أَنْ يُضَمِّدَهَا بِالصَّبِرِ وَزَعَمَ أَنَّ عُثْمَانَ حَدَّثَ عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ فَعَلَ ذَلِكَ
