That the Messenger of Allah announced the death of An-Najashi to the people, and he led thme out and arranged them in rows, and said the Takbir four times. (Using translation from Nasāʾī 1980)
أَنَّ رَسُولَ اللهِ ﷺ «نَعَى لِلنَّاسِ النَّجَاشِيَّ وَخَرَجَ بِهِمْ فَصَفَّ بِهِمْ وَكَبَّرَ أَرْبَعَ تَكْبِيرَاتٍ»
