Why is there any need for Satan in Islam when Allah is the source of evil in Islam?
(If any good reaches them, they say, “This is from Allah,” but if any evil befalls them, they say, “This happened because of you.” Say: “All things are from Allah.” What is wrong with these people that they do not understand any word?) An-Nisa' 78 "
Interesting. Allah is both Satan and god of Islam.
