The Command To Stand Up for A Funeral
أَخْبَرَنَا يُوسُفُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا حَجَّاجٌ، عَنِ ابْنِ جُرَيْجٍ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، وَأَبِي، سَعِيدٍ قَالاَ مَا رَأَيْنَا رَسُولَ اللَّهِ صلى الله عليه وسلم شَهِدَ جَنَازَةً قَطُّ فَجَلَسَ حَتَّى تُوضَعَ .
It was narrated that Abu Hurairah and Abu Sa'eed said: "We never saw the Messenger of Allah attend any funeral where he sat down until (the body) was placed (in the grave)."
