Sunan Abi Dawud, Hadith 3157 ⓘ
Narrated Aisha, Ummul Mu'minin: I saw the Messenger of Allah that he kissed Uthman ibn Maz'un while he was dead, and I saw that tears were flowing (from his eyes).
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ، قَالَتْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يُقَبِّلُ عُثْمَانَ بْنَ مَظْعُونٍ وَهُوَ مَيِّتٌ حَتَّى رَأَيْتُ الدُّمُوعَ تَسِيلُ .
