Sahih al-Bukhari, Hadith 3881 ⓘ
Abu Huraira further said: "Allah's Messenger made them (i.e. the Muslims) stand in rows at the Musalla (i.e. praying place) and led the funeral prayer for the Negus and said four Takbir."
وَعَنْ صَالِحٍ، عَنِ ابْنِ شِهَابٍ، قَالَ حَدَّثَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، أَنَّ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ أَخْبَرَهُمْ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَفَّ بِهِمْ فِي الْمُصَلَّى، فَصَلَّى عَلَيْهِ وَكَبَّرَ أَرْبَعًا.
