Rules of Hunut
591. After having given Ghusl to a dead body it is wajib to give Hunut, which is to apply camphor on its forehead, both the palms, both the knees and both the big toes of its feet. It is not necessary to rub the camphor; it must be seen on those parts. It is Mustahab to apply camphor to the nose tip also. Camphor must be powdered and fresh, and if it is so stale that it has lost its fragrance, then it will not suffice.
592. The recommended precaution is that camphor should first be applied on the forehead of the deceased. It is not necessary to observe sequence while applying camphor to other parts mentioned above.
593. It is better that Hunut is given before Kafan, although there is no harm in giving Hunut during Kafan or even after.
594. It is not permissible to administer Hunut to a person who died in the state of Ihram for Umra and Hajj, except in circumstances explained in rule no. 559.
595. Though it is haraam for a woman to perfume herself if her husband has died and she is in iddah, but if she dies in iddah, it is obligatory to give her Hunut.
596. As a recommended precaution, perfumes like musk, ambergris and aloes-wood ('Ud) should not be applied to the dead body, and these things should not be mixed with camphor.
597. It is Mustahab to mix a small quantity of Turbat (soil of the land around the shrine of Imam Husayn) with camphor, but it should not be applied to those parts of the body, where its use may imply any disrespect. It is also necessary that the quantity of Turbat is not much, so that the identity of camphor does not change.
598. If camphor is not available or the quantity available is just sufficient for Ghusl only, then it is not wajib to apply Hunut. And if it is in excess of the requirement for Ghusl but is not sufficient for administering Hunut to all the parts, then as a recommended precaution, camphor will be applied on the forehead of the dead body first and the remainder, if any, will be applied to other parts.
599. It is also Mustahab that 2 pieces of fresh and green twigs are placed in the grave with the dead body.
