It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that he heard the Noble Prophet (peace and blessings be upon him) say: Whoever knowingly ascribes his lineage to someone other than his father commits disbelief, and whoever claims ownership of something that does not belong to him is not from among us, and he should prepare his abode in Hell. And whoever calls someone a disbeliever or an enemy of Allah, while he is not so, then it returns upon the one who said it.
