فصل في الدفن - ذكر ما يستحب للمرء عند شهود الجنازة أن لا يقعد حتى توضع
Section on burial – Recommendation not to sit until the bier is placed
Hadith 3105
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: Whenever the Prophet Muhammad (peace and blessings be upon him) would go with a funeral, he would not sit down until it was placed in the grave (where the narrator named Abu Muawiyah is in doubt, perhaps these are the words) or until it was buried.
