When Negus died, the Prophet ﷺ said, "Today a pious man has died. So get up and offer the funeral prayer for your brother Ashama."  

قَالَ النَّبِيُّ ﷺ حِينَ مَاتَ النَّجَاشِيُّ مَاتَ الْيَوْمَ رَجُلٌ صَالِحٌ فَقُومُوا فَصَلُّوا عَلَى أَخِيكُمْ أَصْحَمَةَ  

Messenger of Allah ﷺ led the funeral prayer for the Negus and made us stand in rows behind him and I was in the second or third row.  

أَنَّ نَبِيَّ اللَّهِ ﷺ صَلَّى عَلَى النَّجَاشِيِّ فَصَفَّنَا وَرَاءَهُ فَكُنْتُ فِي الصَّفِّ الثَّانِي أَوِ الثَّالِثِ  

The Prophet ﷺ offered the funeral prayer for Ashama, the Negus, with four Takbir.  

أَنَّ النَّبِيَّ ﷺ صَلَّى عَلَى أَصْحَمَةَ النَّجَاشِيِّ فَكَبَّرَ عَلَيْهِ أَرْبَعًا  

that Messenger of Allah ﷺ informed them (i.e. his companions) of the death of Negus, the king of Ethiopia, on the very day on which the latter died, and said, "Ask Allah's Forgiveness for your brother"  

أَنَّ أَبَا هُرَيْرَةَ ؓ أَخْبَرَهُمَا أَنَّ رَسُولَ اللَّهِ ﷺ نَعَى لَهُمُ النَّجَاشِيَّ صَاحِبَ الْحَبَشَةِ فِي الْيَوْمِ الَّذِي مَاتَ فِيهِ وَقَالَ اسْتَغْفِرُوا لأَخِيكُمْ  

"Messenger of Allah ﷺ 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."  

أَنَّ أَبَا هُرَيْرَةَ ؓ أَخْبَرَهُمْ أَنَّ رَسُولَ اللَّهِ ﷺ صَفَّ بِهِمْ فِي الْمُصَلَّى فَصَلَّى عَلَيْهِ وَكَبَّرَ أَرْبَعًا
