Sayyiduna Abu Dharr (may Allah be pleased with him) reports that the Noble Prophet (peace and blessings be upon him) said: Whoever knowingly claims someone other than his father as his father, he has committed disbelief; and whoever associates his lineage with a people to whom he has no (blood) relation, then he should take his place in Hell.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: "Let none of you deny his father, for whoever turns away from his father (and claims to be the son of another), this is disbelief."

Sayyiduna Sa’d (may Allah be pleased with him) narrated that I heard the Prophet (peace and blessings of Allah be upon him) say: Whoever claims to be the son of anyone other than his (real) father, knowing that he is not his father, then Paradise is forbidden for him. Then this hadith was mentioned to Sayyiduna Abu Bakrah (may Allah be pleased with him), so he said: Both my ears heard this hadith from the Prophet (peace and blessings of Allah be upon him), and my heart has preserved it.
