Fathwa - Some jurists recommend stuffing the deceased holes with cotton

Question
Why is cotton placed in the mouth and the nose of the deceased?
Answer
All perfect praise be to Allaah, The Lord of the Worlds. I testify
that there is none worthy of worship except Allaah, and that Muhammad,
is His Slave and Messenger.
Some jurists recommended stuffing the deceased's holes withcotton so
as to block the inner liquids and odors. Moreover, they recommended
putting perfumes and camphor on the cotton.
Such recommendation was narrated on the authority of some righteous
predecessors;Al-Hasansaid: "It is recommended to stuff the anus, ears
and nose of the deceased."Ibn Seereen, may Allaah havemercy upon him,
also narrated that: "It is recommended to stuff the anus, mouth and
nose of the deceased with cotton." ]Ibn Abi Shaybah[
However, there is no evidence supporting this view. Therefore, this
should not be applied unless there is fear that something will leak
from the body of the deceased; so as to ward off the harm.
The Hanbali scholar,Al-Buhooti, may Allaah have mercy upon him, said:
"If there is fear that some blood may come out of his facial
apertureslike the mouth and nose, there is nothing wrong with stuffing
them with cotton to ward off the harm."
Allaah Knows best.
