Need a reference for a hadith about staying at the grave after burial

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.
