Hadith 1914
Chapter 44: Hastening With The Janazah - كتاب الجنائز
أَخْبَرَنَا يَحْيَى بْنُ دُرُسْتَ، قَالَ حَدَّثَنَا أَبُو إِسْمَاعِيلَ، عَنْ يَحْيَى، أَنَّ أَبَا سَلَمَةَ، حَدَّثَهُ عَنْ أَبِي سَعِيدٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا مَرَّتْ بِكُمْ جَنَازَةٌ فَقُومُوا فَمَنْ تَبِعَهَا فَلاَ يَقْعُدْ حَتَّى تُوضَعَ " .
It was narrated from Abu Sa'eed that the Messenger of Allah said:
"When a funeral passes by you, stand up, and whoever follows it, let him not sit down until it is put down (in the grave)."
