The Messenger of Allah said: “Whoever washes a deceased person and covers his shortcomings,  Allah will forgive him forty times. And whoever shrouds the deceased,  Allah will clothe him in garments of silk brocade in Paradise. And  whoever digs a grave for the deceased and lowers him into it, Allah  will give a continuous reward, like the reward of someone who houses  another person, until the Day of Judgement.”
