"O you who have believed, whoever of you should revert from his religion - Allaah will bring forth [in place of them] a people He will love and who will love Him [who are] humble toward the believers, powerful against the disbelievers; they strive in the cause of Allaah and do not fear the blame of a critic. That is the favor of Allaah ; He bestows it upon whom He wills. And Allaah is all-Encompassing and Knowing."

(Surah Al-Ma'idah, Ayah: 54)
