Ibrahim (Abraham) - Abraham Reasons With His Father

All was finished between Abraham and his people and the struggle began. The most amazed and furious was his father (or his uncle who had raised him), for, as it is well known, he not only worshipped idols but sculptured and sold them as well. Abraham felt that it was his duty as a good son to advise his father against this evil so that he could be saved from Allah's punishment.
Being a wise son, he did not make his father feel foolish, nor did he openly laugh at his conduct. He told him that he loved him, thereby hoping to generate fatherly love. Then he gently asked him why he worshipped lifeless idols who could not hear, see, or protect him. Before his father could become angry he hastily added: "0 my father! Verily! There has come to me of knowledge that which came not unto you. So follow me. I will guide you to a Straight Path. 0 my father! Worship not Satan. Verily! Satan has been a rebel against the Most Beneficent (Allah). 0 my father! Verily! I fear lest a torment from the Most Beneficent (Allah) overtake you, so that you become a companion of Satan (in the Hell-Fire)."
He (the father) said: "Do you reject my gods, 0 Abraham? If you stop not (this), I will indeed stone you. So get away from me safely before I punish you." Abraham said: "Peace be on you! I will ask Forgiveness of my Lord for you. Verily! He is unto me, Ever Most Gracious. And I shall turn away from you and from those whom you invoke besides Allah. Surah 19: 43-48
