حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَعَى لِلنَّاسِ النَّجَاشِيَ فِي الْيَوْمِ الَّذِي مَاتَ فِيهِ فَخَرَجَ بِهِمْ إِلَى الْمُصَلَّى وَكَبَّرَ أَرْبَعَ تَكْبِيرَاتٍ .
Abu Huraira reported that the Messenger of Allah (ﷺ) gave the people news of the death of Negus on the day he died, and he took them out to the place of prayer and observed four takbirs.
