God says in the holy Qu'ran: " Fain would they put out the light of Allah with their mouths, but Allah disdaineth (aught) save that He shall perfect His light, however much the disbelievers are averse. . He it is who hath sent His messenger with the guidance and the Religion of Truth, that He may cause it to prevail over all religion, however much the idolaters may be averse. " [9/32-33].
