Hadith 3:39
Salim narrated on the authority of his father (RAA) that he saw the Messenger of Allah (ﷺ), Abu Bakr and ’Umar walking in front of a Funeral.’ Related by the five Imams, and Ibn Hibban rendered it Sahih.
وَعَنْ سَالِمٍ, عَنْ أَبِيهِ - رضى الله عنه - { أَنَّهُ رَأَى اَلنَّبِيَّ - صلى الله عليه وسلم -وَأَبَا بَكْرٍ وَعُمَرَ, يَمْشُونَ أَمَامَ الْجَنَازَةِ } رَوَاهُ اَلْخَمْسَةُ، وَصَحَّحَهُ ابْنُ حِبَّانَ, وَأَعَلَّهُ النَّسَائِيُّ وَطَائِفَةٌ بِالْإِرْسَالِ
