The methodology of Abraham in calling to Allah

{ And mention in the Book [the story of] Abraham. Indeed, he was a man of truth and a prophet. [Mention] when he said to his father, "O my father, why do you worship that which does not hear and does not see and will not benefit you at all? O my father, indeed there has come to me of knowledge that which has not come to you, so follow me; I will guide you to an even path. O my father, do not worship [i.e., obey] Satan. Indeed Satan has ever been, to the Most Merciful, disobedient. O my father, indeed I fear that there will touch you a punishment from the Most Merciful so you would be to Satan a companion [in Hellfire]." }
