2. Sahl has narrated from certain persons of his people from abu Hammam ’Isma‘il ibn Hammad who has said the following
“Abu Ja‘far (a.s.), when about to leave this world said, ‘When I die dig a grave for me as a straight cut in the ground, as opposed to digging straight and then digging horizontally a passage to accommodate the body which is called Lahad. If people say that the Messenger of Allah was place in Lahad, accept it as true.’”
