Sunan an-Nasa'i 1970

أَخْبَرَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، عَنْ حَفْصِ بْنِ غِيَاثٍ، عَنِ ابْنِ جُرَيْجٍ، عَنْ عَطَاءٍ، عَنْ جَابِرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِنَّ أَخَاكُمُ النَّجَاشِيَّ قَدْ مَاتَ فَقُومُوا فَصَلُّوا عَلَيْهِ ‏"‏ ‏.‏ فَقَامَ فَصَفَّ بِنَا كَمَا يُصَفُّ عَلَى الْجَنَازَةِ وَصَلَّى عَلَيْهِ ‏.‏

It was narrated from Jair that:the Messenger of Allah said: "Your brother An-Najashi has died, so get up and offer the funeral prayer for him." He stood up and put us in rows as is done for the funeral prayer, and we prayed for him
