Say (O Muhammad SAW): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [(i.e. one should follow only the Quran and the Sunnah (legal ways, orders, acts of worship, statements of Prophet Muhammad SAW, as the Companions of the Prophet SAW did)].
