وَعَنْ أَبِي هُرَيْرَةَ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَعَى لِلنَّاسِ النَّجَاشِيَّ الْيَوْمَ الَّذِي مَاتَ فِيهِ وَخرج بِهِمْ إِلَى الْمُصَلَّى فَصَفَّ بِهِمْ وَكَبَّرَ أَرْبَعَ تَكْبِيرَات

He said the Prophet gave the people news of the death of the Negus on the day on which he died, took them out to the place of prayer, drew them up in rows and said “God is most great” four times. (Bukhari and Muslim.)
