Question: Is there reward in attending the funeral procession of someone that commits acts of shirk and innovation?
Response: Do not attend a funeral procession of someone that commits clear acts of shirk. However, if the person has committed some sins or innovations that do not remove him from the fold of Islam, then attend his funeral. At the same time, it is okay for the imam and dignitaries to abstain from attending, but the rest of the Muslims should pray over him.
