Al-Anbiya 21:45 قل انما انذركم بالوحي ولا يسمع الصم الدعاء اذا ما ينذرون ٤٥

Say (O Muhammad صلى الله عليه وسلم): "I warn you only by the revelation (from Allâh 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 Qur’ân and the Sunnah (legal ways, orders, acts of worship, and the statements of Prophet Muhammad صلى الله عليه وسلم, as the companions of the Prophet صلى الله عليه وسلم did)]¹.
