The quantity of Sidr and caphor should neither be so much that the water becomes mixed (Muèàf), nor so little that it may be said that Sidr and caphor have not been mixed in it at all. Aperson who gives Ghusl to a dead body should be a Muslim and sane and as a precaution a Shi'ah Ithna-Ashariyyah, and ahould know the rules of Ghusl. One who gives Ghuls to the dead body should perform the act with the intention of Qurbah, and it is enough to be with intention of complying with the God's will.
Ghusl to a Muslim dead child, even illegitimate, is obligatory. If a foetus of 4 months or more is aborted it is obligatory to give it Ghuls, and even if it has not completed four months, but it has formed features of a human child, it must be given Ghusl as a precaution. In the event of both of these circumstances being absent, the foetus will be wrapped up in a cloth and buried without Ghusl.
It is unlawful for a man to give Ghusl to the dead body of a non-Mahram woman and for a woman to give Ghusl to the dead body of a non-Mahram man. Husband and wife can, however, give Ghusl to the dead body of each other. If there is an essential impurity on any part of the dead body, it is obligatory to remove it befor giving Ghusl. Ghusl for a dead body is similar to Ghusl of Janàbah.
And the obligatory precaution is that a corpse should not be given Ghusl by Irtimàsi',that is, immersion, as long as it is possible to give Ghusl by way of Tartibi. And even in the case of Tartibi Ghusl it is necessary that the body should be washed on the right side first. And then the left side.
There is no rule for Jabi'rah in Ghusl of mayyit, so if water is not available or there is some other valid excuse for abstaining from using water for the Ghusl, then the dead body should be given one Tayammum instead of Ghusl. A perscon giving Tayammum to the dead body should strike his own palms on earth and then wipe them the face and back of the hands of the daed body. And the recommended precaution is that he should, if possible, use the hands of the dead for another Tayammum.
Rules Regarding Kafn (Shrouding) The body of a dead Muslim should be given Kafn with three pieces of cloth:a loin cloth, a shirt or tunic, and a full cover. As an obligatory precaution, the loin cloth should be long enough to cover the body from the navel up to the knees, better still if it covers the body from the chest up to the feet.
