If you follow the right guidance and enjoin what is right (Islamic Monotheism and all that Islam orders one to do) and forbid what is wrong (polytheism, disbelief and all that Islam has forbidden) no hurt can come to you from those who are in error. The return of you all is to Allah, then He will inform you about (all) that which you used to do.
