I was taught to recite [14:40-41] in my salah:
Our Lord, forgive me and my parents and the believers the Day the account is established." [14:41]
And the verse 9:113 says I cannot ask forgiveness for non-believers after they have passed away.
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.[9:113]
How can a person with non-muslim parents recite 14:41 in his salah or in general when it contradicts ayah 9:113 (the rule that he cannot ask forgiveness for dead non-muslims)?
