Nubaih b Wahb reported that the eyes of Umar b. Ubaidnllah b. Ma'mar were swollen, and he decided to use antimony. Aban b. 'Uthman forbade him to do so and commanded him to apply aloes on them, and reported on the authority of 'Uthman b. Affan that the Messenger of Allah ﷺ had done that.
حَدَّثَنِي نُبَيْهُ بْنُ وَهْبٍ أَنَّ عُمَرَ بْنَ عُبَيْدِ اللَّهِ بْنِ مَعْمَرٍ رَمِدَتْ عَيْنُهُ فَأَرَادَ أَنْ يَكْحُلَهَا فَنَهَاهُ أَبَانُ بْنُ عُثْمَانَ وَأَمَرَهُ أَنْ يُضَمِّدَهَا بِالصَّبِرِ وَحَدَّثَ عَنْ عُثْمَانَ بْنِ عَفَّانَ عَنِ النَّبِيِّ ﷺ أَنَّهُ فَعَلَ ذَلِكَ
