For example in India there are many beliefs and one of them is the Siekh (people nvere cut their head hair), they believe that the brother can have an affair with his brother wife.
In UAS a Siekh man killed his brother because his wife like his brother more than him.
God (Allah) is great creator how can we compare or dare to compare God (Allah) with someone who did not creat anything?
Can some one be greater than his God? In China yes because there are people who worship snakes and I think they kill the snakes any time.
Let us use common sense and be logical.
