There passed a bier and the Prophet (ﷺ) stood up for it and we also stood up along with him. We said: Messenger of Allah, that was the bier of a Jewess. Upon this he remarked: Verily, death is a matter of consternation, so whenever you come across a bier stand up.
Ibn Juraij told me that Abu Zubair heard Jabir say that the Prophet (ﷺ) kept standing for a bier until it disappeared.
Anas reported that the Messenger of Allah (ﷺ) observed prayer on the grave.
Lead me to her (or his) grave. They led him to that place and he said prayer over her (or him) and then remarked: Verily, these graves are full of darkness for their dwellers. Verily, the Mighty and Glorious Allah illuminates them for their occupants by reason of my prayer over them.
The Messenger of Allah (ﷺ) recited thus.
Whenever you see a funeral procession, stand up for that until it moves away or is lowered on the ground.
Should any one of you come across a funeral procession, and if he does not intend to accompany it, he must stand up until it passes by him or is placed upon the ground before it passes him.
Should anyone amongst you see a bier he must stand up so long as it is within sight in case he does not intend to follow it.
When you follow a bier, do not sit until it is placed on the (ground).
There died today the pious servant of Allah, Ashama. So he stood up and led us in (funeral prayer) over him.
