11. A number of our people have narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “Abu ‘Abd Allah (a.s.), has said that when you place a deceased in the grave say, ‘O Allah [this is] Your servant son of a male servant and a female servant who has become Your guest and You are the best host.’ When you send the body upward from where the feet are to be placed to the place for the head say, ‘(I begin) in the name of Allah, with Allah and according to the tradition of the Messenger of Allah. O Allah, (send him) to Your mercy but not to Your punishment. O Allah, make his grave spacious, dictate him the statement of his authority, make him steadfast upon the solid words, protect him and us against the torment of fire.’ When earth is leveled upon him say, ‘O Allah, make the earth spacious on his both sides. Raise his spirit toward the spirits of the believing people in the high places and join him with righteous ones.’”
