Al-Qarni: "At any rate, if we return to our discussion of the heart of the matter? First of all, we must realize that Allah obligated us to disseminate this religion all over the globe. And first, it should be spread through outreach and calling people to Allah's word, through pleasing words, gently, and through good deeds. Through letting people hear Allah's words and showing them Islam. However, if we run up against someone who opposes this path and attempts to obstruct the spread of the upright religion and the light, and to obstruct their reaching others ? in this case it is a duty to fight such a person. And Allah said: 'Fight them until there is no more strife and Allah's religion reigns supreme.'
"We don't agree with those who disavow this completely and say that the religion [of Islam] doesn't use the sword. No. Islam uses the sword when there is no other alternative. Therefore wisdom, as the religious authorities say, consists in utilizing each thing in its proper place. If there is need for the sword, then it is wise to use the sword, and if the occasion requires kind words and outreach, then it is wise to utilize them."
