Uthman bin Muhammad Abi Shayba narrates from Jarir bin Abdul Hameed al-Razi narrating from Suhayl bin Abi Salah narrating from Dhakwan Abu Salah al-Saman al-Ziyat narrating from Abu Said al-Khudri.
It is narrated on the authority of Abu Sa'id al-Khudri that the Holy Prophet (may peace be upon him) said: When you follow a bier, do not sit until it is placed on the (ground).
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا اتَّبَعْتُمْ جَنَازَةً فَلاَ تَجْلِسُوا حَتَّى تُوضَعَ " .
