The shroud how to, Kaffan How to
Sahl ibn Sa‘d may Allaah be pleased with him reported that a woman brought a woven piece of cloth to the Messenger of Allaah, sallallaahu ‘alayhi wa sallam, and said to him: "I have woven this sheet with my own hands for you to wear". He, sallallaahu ‘alayhi wa sallam, accepted it as he was in need of it. Later on he, sallallaahu ‘alayhi wa sallam, came out wearing it as a lower garment. Someone said: "How nice it is! Kindly give it to me." The people said (to that man): "You did not do well; The Messenger of Allaah, sallallaahu ‘alayhi wa sallam, wore it and he was in need of it, then you asked him for it though you are well aware that he, sallallaahu ‘alayhi wa sallam, never refuses a request." The man said: "I swear by Allaah that I did not ask for it to wear it. I asked him for it so that it would be my shroud after my death." Sahl may Allaah be pleased with him (the narrator of this Hadith) said: “And, in fact, it was used as his shroud”. [Al-Bukhari].
This Hadeeth indicates the permissibility of preparing one`s shroud before death.
