ʿUmar bin ʿUbaidullah sent word to Aban bin ʿUthman ؓ , (to ask) whether he could apply something to his eyes when he was in ihram - or (to ask) what he could apply to his eyes when he was in ihram. He sent word back to him telling him that he could apply aloes to them, and I heard ʿUthman bin Affanؓ narrating that from the Messenger of Allah ﷺ .
عَنْ نُبَيْهِ بْنِ وَهْبٍ قَالَأَرْسَلَ عُمَرُ بْنُ عُبَيْدِ اللهِ إِلَى أَبَانَ بْنِ عُثْمَانَ أَيُكَحِّلُ عَيْنَيْهِ وَهُوَ مُحْرِمٌ؟ أَوْ بِأَيِّ شَيْءٍ يُكَحِّلُهُمَا وَهُوَ مُحْرِمٌ؟ فَأَرْسَلَ إِلَيْهِ أَنْ يُضَمِّدَهُمَا بِالصَّبِرِ فَإِنِّي سَمِعْتُ عُثْمَانَ بْنَ عَفَّانَ يُحَدِّثُ ذَلِكَ عَنْ رَسُولِ اللهِ ﷺ
