Hadith 6:713
Hafs narrated to us, from Ash'ath, from Ibn Sirin and Ibn Hubayrah, from Ibn Umar, that when he would accompany a funeral procession, he would not sit down until the bier was placed on the ground.
حدثنا حفص عن أشعث عن بن سيرين وبن هبيرة عن بن عمر أنه كان إذا صحب جنازة لم يجلس حتى يوضع السرير
