The Messenger of Allah ﷺ gave the people news of death of Negus on the day on which he died, took them out to the place of prayer, drew them up in rows and said: "Allah is Most Great" four times.
أَنَّ رَسُولَ اللَّهِ ﷺ نَعَى لِلنَّاسِ النَّجَاشِيَّ فِي الْيَوْمِ الَّذِي مَاتَ فِيهِ وَخَرَجَ بِهِمْ إِلَى الْمُصَلَّى فَصَفَّ بِهِمْ وَكَبَّرَ أَرْبَعَ تَكْبِيرَاتٍ
