It is not proper for the Prophet and those who believe that they should beg forgiveness for the mushrikïn, even though they be their relatives, after it has been explained to them that they are the inmates of hellfire. Abraham prayed for his father’s forgiveness only to fulfill a promise he had made to him. But when it became clear to him that he was an enemy of Allah he disassociated himself from him. The fact is that Abraham was tenderhearted, forbearing. It is not the way of Allah to confound people after He has guided them, until He makes clear to them what they should guard against; surely Allah has the knowledge of everything. Surely it is Allah to Whom belongs the kingdom of the heavens and the earth. He gives life and causes to die. You have none besides Allah to protect or to help.
