Sayyiduna Abu Dharr (may Allah be pleased with him) narrates that I heard the Noble Prophet (peace and blessings be upon him) say: Whoever knowingly ascribes himself to anyone other than his father, for him there is nothing but disbelief. Whoever claims something that does not rightfully belong to him, he is not from among us, and he should take his place in Hell. And whoever calls someone a disbeliever or an enemy of Allah, while he is not so, then the speaker himself will be subject to what he said.
