"And slay them wherever ye catch them.." (2:191)
A classic and popular example of what Muslim scholars, like Dr. Jamal Badawi, call a ‘cut and paste’ approach. Everything becomes so much easier for the Anti-Islamists when they remove the context. The solution for the Muslim [ and anyone else wishing to understand] is to simply replace the verse in its context:
2:190-194 Fight in the cause of God those who fight you, but do not transgress limits; for God loves not transgressors. And kill them wherever ye catch them, and turn them out from where they have turned you out; for persecution and oppression are worse than slaughter; but fight them not at the Sacred Mosque, unless they (first) fight you there; but if they fight you, kill them. Such is the reward of those who reject faith. But if they cease, God is Oft-Forgiving, Most Merciful. And fight them on until there is no more tumult or oppression, and there prevail justice and faith in God; but if they cease, let there be no hostility except to those who practice oppression. The prohibited month, for the prohibited month, and so for all things prohibited, there is the law of equality. If then any one transgresses the prohibition against you, transgress ye likewise against him. But fear (the punishment of) God, and know that God is with those who restrain themselves.
How many times do we see the above verse repeating the message to make it clear? These verse were revealed at a time when Muslims of Madinah were under constant attack from the Makkans. An example would be when the Makkans conducted the public crucifixion of the companion of the Prophet Muhammad (peace be upon him), Khubaib bin Adi. These would be classified as 'terrorist activities' according to the modern usage of the term. So what does this verse say in this context? "Fight in the cause of God those who fight you", "unless they (first) fight you there" - the context of this verse applies to those who initiate the attack against Muslims. And even after they attack, the verse makes it clear: "But if they cease, God is Oft-Forgiving, Most Merciful." And it also makes clear the purpose for what Muslims fight: "fight them on until there is no more tumult or oppression, and there prevail justice and faith in God". It is the duty of Muslims to defend humanity from oppression and persecution and to establish justice. Muslims believe that God has placed us here on earth as his deputy or viceroy, and thus, it is our duty to enjoin the good and forbid the evil, to establish peace and justice in the land. Dr. Maher Hathout writes the following on verses 2:190-194:
These verses were applicable to a particular situation or if, hypothetically, the same situation was to be repeated… Historically, fighting back against the aggressors was prohibited during the thirteen years of the Meccan period. After the migration to Medina and the establishment of the Islamic state, Muslims were concerned with how to defend themselves against aggression from their enemies. The aforementioned verses were revealed to enable them to protect the newly formed state by fighting in self-defence against those who fought them. However, the Qur’an clearly prohibits aggression. The verses explain that fighting is only for self-defence. Thus, a Muslim cannot commit aggression and kill innocent men, women, children, the sick, the elderly, monks, priests, or those who do not wish to fight...."
The fact that some deranged highly financially subsidised cretins presently act against these directives should not be levelled at the Islamic religion as a whole.
