‘A’isha said that God’s messenger kissed ‘Uthman b. Maz'un (The first of the Emigrants to die in Medina after returning from Badr) when he was dead, and the Prophet (ﷺ) wept so much that his tears flowed over ‘Uthman's face. Tirmidhl, Abu Dawud and Ibn Majah transmitted it.

وَعَنْ عَائِشَةَ قَالَتْ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَبَّلَ عُثْمَانَ بْنَ مَظْعُونٍ وَهُوَ مَيِّتٌ وَهُوَ يَبْكِي حَتَّى سَالَ دُمُوعُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى وَجْهِ عُثْمَانَ. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَابْنُ مَاجَهْ
