Dealing with a sorcerer neighbor

Q 5: How should a Muslim treat Muslim neighbors who practice sorcery and charlatanry? Should they stand by them during times of grief or happiness, as we paid our condolences to our neighbors on the death of a relative? Will we be rewarded for consoling them or was this not permissible?

A: It is obligatory on a Muslim to disapprove of any Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect) committed by neighbors or others, until they abstain from this; but at the same time they have to treat them kindly, as entailed by neighborhood rights.
