صحيح مسلم 217

It is reported on the authority of Abu Dharr that he heard the Messenger of Allah (may peace and blessings be upon him) saying:No person who claimed knowingly anyone else as his father besides (his own) committed nothing but infidelity, and he who made a claim of anything, which (in fact) did not belong to him, is not amongst us; he should make his abode in Fire, and he who labeled anyone with unbelief or called him the enemy of Allah, and he was in fact not so, it rebounded on him

Rapporté par Abu Dharr رضي الله عنه : Il a entendu le Messager d’Allah ﷺ dire : Celui qui prétend sciemment qu’une autre personne est son père alors que ce n’est pas le cas commet un acte d’incroyance. Celui qui revendique ce qui ne lui appartient pas ne fait pas partie de nous ; qu’il prenne sa place en Enfer. Et celui qui traite quelqu’un d’incroyant ou d’ennemi d’Allah alors que ce n’est pas vrai, cela se retourne contre lui
