An Illegitimate Child Will Never Enter The Paradise?
There’s no such narration in my knowledge. Even if one exists, it might have been misunderstood because it goes against the Quran. Quran 6:164 Ask them: Should I seek some other Lord than God when He alone is the Lord of everything? [I have fulfilled my duty. If you do not accept, then you should know that] each person is responsible for what he earns and no soul shall bear another’s burden . Then to your Lord shall all of you must return.
The narration is part of musnd ahmed ibn hanbal and is numbered 6655 but you already clarified it wrt to quranic injunction.
