Sahih Muslim , Book 11, Hadith 83 (In-Book) ⓘ
Abu Huraira reported: The Messenger of Allah gave us the news of the death of Negus, the ruler of Abyssinia, on the day when he died, and he said (to us): Beg pardon for your brother. Ibn Shihab said that Sa'id b. Musayyib had told that Abu Huraira had narrated to him that the Messenger of Allah drew them up in a row in a place of prayer, and offered prayer and recited four takbirs for him.
وَحَدَّثَنِي عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ، حَدَّثَنِي أَبِي، عَنْ جَدِّي، قَالَ حَدَّثَنِي عُقَيْلُ، بْنُ خَالِدٍ عَنِ ابْنِ شِهَابٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَأَبِي، سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ أَنَّهُمَا حَدَّثَاهُ عَنْ أَبِي هُرَيْرَةَ، أَنَّهُ قَالَ نَعَى لَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم النَّجَاشِيَ صَاحِبَ الْحَبَشَةِ فِي الْيَوْمِ الَّذِي مَاتَ فِيهِ فَقَالَ " اسْتَغْفِرُوا لأَخِيكُمْ " . قَالَ ابْنُ شِهَابٍ وَحَدَّثَنِي سَعِيدُ بْنُ الْمُسَيَّبِ أَنَّ أَبَا هُرَيْرَةَ حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَفَّ بِهِمْ بِالْمُصَلَّى فَصَلَّى فَكَبَّرَ عَلَيْهِ أَرْبَعَ تَكْبِيرَاتٍ .
