Volume 4, Book 56, Number 685:
Narrated Ribi bin Hirash:
‘Uqba said to Hudhaifa, “Won’t you narrate to us what you heard from Allah’s Apostle ?” Hudhaifa
said, “I heard him saying, ‘Death approached a man and when he had no hope of surviving, he said
to his family, ‘When I die, gather for me much wood and build a fire (to burn me),. When the fire has
eaten my flesh and reached my bones, take the bones and grind them and scatter the resulting
powder in the sea on a hot (or windy) day.’ (That was done.) But Allah collected his particles and
asked (him), ‘Why did you do so?’ He replied, ‘For fear of You.’ So Allah forgave him.”
