Sunan Abi Dawud, Hadith 1834

Nubaih bin Wahb said ‘Umar bin ‘Ubaid Allah bin Ma’mar had a complaint in his eyes. He sent (someone) to Aban bin ‘Uthman - the narrator Sufyan said that he was the chief of pilgrims during the season of Hajj – asking him what he should do with them. He said Apply aloes to them, for I heard ‘Uthaman narrating this on the authority of the Apostle of Allaah.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ بْنِ مُوسَى، عَنْ نُبَيْهِ بْنِ وَهْبٍ، قَالَ اشْتَكَى عُمَرُ بْنُ عُبَيْدِ اللَّهِ بْنِ مَعْمَرٍ عَيْنَيْهِ فَأَرْسَلَ إِلَى أَبَانَ بْنِ عُثْمَانَ - قَالَ سُفْيَانُ وَهُوَ أَمِيرُ الْمَوْسِمِ - مَا يَصْنَعُ بِهِمَا قَالَ اضْمِدْهُمَا بِالصَّبِرِ فَإِنِّي سَمِعْتُ عُثْمَانَ - رضى الله عنه - يُحَدِّثُ ذَلِكَ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
