No matter how immoral or hostile others behaving, a Muslim is supposed to only act justly.
"O You who believe! Show integrity for the sake of God, bearing witness with justice. Do not let hatred for a people incite you into not being just. Be just. That is closer to faith. Heed God [alone]. God is aware of what you do."(Quran, 5:8)
The existence of hypocritical people who emerge in the name of God and religion, but actually organise themselves to commit wickedness condemned by Allah, is indicated in the Quran. One verse talks about a gang of nine men who planned to murder the Prophet by swearing in the name of God:
“There was a gang of nine men in the city causing corruption in the land and not putting things right. They said, “Let us make an oath to one another by God that we will fall on him and his family in the night and then say to his protector, We did not witness the destruction of his family and we are telling the truth.” They hatched a plot and We hatched a plot while they were not aware."(Quran, 27:48-50)
As this incident described in the Quran reveals, the fact that people do things "in the name of God" or even swear in His name, in other words that they use the kind of language designed to show themselves as very religious, does not mean that what they do is in conformity with religion. On the contrary, what they do can be quite against the will of God and the morality of religion.
This being the case, it is obvious what great sins are the murde
