Rules About Burial of the Dead Body
620. * It is obligatory to bury a dead body in the ground, so deep that its smell does not come out and the beasts of prey do not dig it out, and, if there is a danger of such beasts digging it out then the grave should be made solid with bricks, etc.

621. If it is not possible to bury a dead body in the ground, it may be kept in a vault or a coffin, instead.

622. The dead body should be laid in the grave on its right side so that the face remains towards the Qibla.

623. * If a person dies on a ship and if there is no fear of the decay of the dead body and if there is no problem in retaining it for sometime on the ship, it should be kept on it and buried in the ground after reaching the land. Otherwise, after giving Ghusl, Hunut, Kafan and Namaz-e-Mayyit it should be lowered into the sea in a vessel of clay or with a weight tied to its feet. And as far as possible it should not be lowered at a point where it is eaten up immediately by the sea predators.
