the grave once it has been dug to the depth of a man’s height plus an arm’s reach; the surface of the grave is left level, with no structure erected over it and no plaster applied. There is no harm in weeping for the deceased so long as it does not involve wailing or the tearing of garments. The family may be offered condolences for up to three days after the burial, and two people are not placed in the same grave unless necessity requires it.
