There be no compulsion in religion This is what quran says. In Surah 2 256. LET THERE BE NO COMPULSION IN RELIGION: Truth stands out clear from Error: whoever rejects evil and believes in Allah hath grasped the most trustworthy hand-hold, that never breaks. And Allah heareth and knoweth all things. Translation taken from http://www.harunyahya.com/Quran_translation/Quran_translation_index.php
