Ruling on using bukhoor (incense) to expel devils

I do not know of any basis in sharee’ah for doing this, and
it should not be done, because it is a myth that has no basis. Devils can
only be expelled by reciting a lot of dhikr and reading Qur’aan and seeking
refuge in the perfect words of Allaah from the evil of that which He has
created. It is proven that the Prophet (peace and blessings of Allaah
be upon him) said: “Whoever stops to rest and
says, ‘A’oodhu bi kalimaat Allaah il-taammah
min sharri ma khalaq  (I seek refuge in the perfect words of Allaah from the
evil of that which He has created),’ nothing will harm him until he moves on
from that place.”  A man said:
O
Messenger of Allaah, I was stung by a scorpion last night. He said: “If you
had said, A’oodhu bi kalimaat Allaah al-taammah min sharri ma khalaq
(I seek refuge in the perfect words of Allaah from the evil of that which He
has created), it would not have harmed you.” And he (peace and
blessings of Allaah be upon him) said: “Whoever says in the morning, ‘Bismillaah
illaahi laa yadurru ma’a ismihi shay’un fi’l-ard wa la fi’l-sama’ wa huwa
al-samee’ ul-‘aleem (In the name of Allaah with Whose name nothing is
harmed on earth nor in heaven, and He is the All-Hearing, All-Knowing)’
three times, nothing will
harm him until evening comes, and whoever says it when evening comes,
nothing will harm him until morning comes.” 

I ask Allaah to help us and you
and all of our brothers to attain beneficial knowledge and act upon it, for
He is All hearing and Ever Near. End quote.
