Sayyiduna Wathilah bin Asqa’ (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) say:
Indeed, the greatest lie (he said this three times, then said:) is that a man lies about himself: that he says,“I saw such-and-such dream,”while he did not see anything in his dream; or a man falsely claims something about his parents so that he may be attributed to someone other than his father; or a person says that he heard something (i.e., a hadith) from me, while he did not hear it from me.
