And (during war) kill (the disbelievers) wherever you find them, and drive them out from where they drove you out. And rousing mischief and disruption is a severer (crime) than killing. But do not fight against them in the proximity of the Sacred Mosque (Ka‘ba) unless they themselves fight there against you. Then if they attack you, kill them, for that is the right penalty of (such) disbelievers.
