I recently came across a quote on FB that was claimed as being a hadith. The summary of the quote was that after the janazah and burial of one's deceased parent, one should stay at their grave, reciting surahs and duas for them for such an amount of time that is equivalent to the time it takes a person to slaughter a camel, skin it and to cut and distribute its meat. Otherwise, the deceased feels as if they have been set adrift in the sea without any support. I wanted to confirm whether this is actually a hadith or not, before forwarding it to others.
There is a hadith in Sahih Muslim wherein 'Amr bin Al-'As says to his son:
When you bury me, fill my grave well with earth, then stand around it for the time within which a camel is slaughtered and its meat is distributed so that I may enjoy your intimacy and (in your company) ascertain what answer I can give to the messengers (angels) of Allah.
However, this single narration doesn't indicate that this is a blessed act or something ordained by the prophet, simply a personal request by 'Amr bin Al-'As himself.
