Surah At-Tawba Ayahs #117 Translated in English

It is not for the Prophet and those who have believed to ask forgiveness for the polytheists, even if they were relatives, after it has become clear to them that they are companions of Hellfire.

And the request of forgiveness of Abraham for his father was only because of a promise he had made to him. But when it became apparent to him [i.e., Abraham] that he [i.e., the father] was an enemy to Allāh, he disassociated himself from him. Indeed was Abraham compassionate and patient.

And Allāh would not let a people stray after He has guided them until He makes clear to them what they should avoid. Indeed, Allāh is Knowing of all things.

Indeed, to Allāh belongs the dominion of the heavens and the earth; He gives life and causes death. And you have not besides Allāh any protector or any helper.

Allāh has already forgiven the Prophet and the Muhājireen and the Anṣār who followed him in the hour of difficulty after the hearts of a party of them had almost inclined [to doubt], and then He forgave them. Indeed, He was to them Kind and Merciful.
