9:123O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty (unto Him).
66:9O Prophet! Strive against the disbelievers and the hypocrites, and be stern with them. Hell will be their home, a hapless journey's end.
