Ibrahim (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 Ibrahim was tenderhearted, forbearing.

As for Abraham's prayer for his father's forgiveness, it was only in fulfilment of a promise he had made to him. But when it became clear to Abraham that his father was an enemy of Allah, he broke ties with him.1 Abraham was truly tender-hearted, forbearing.
