It is narrated from Sayyiduna Asim bin Adi (may Allah be pleased with him) that he was with the Messenger of Allah (peace and blessings be upon him). When this verse was revealed: "and then they do not bring four witnesses," I said: "O Messenger of Allah! (Is the ruling) that until they bring four witnesses? (By then) the wretch will have fulfilled his need." The narrator says: He had not yet got up from there when his cousin (the son of his paternal uncle) came with his wife, who was carrying a child. The woman was saying: "He is yours," while he (the husband) was saying: "He is not mine." So the verse of li'an was revealed. Sayyiduna Asim (may Allah be pleased with him) said: "I am the first person who spoke about this, and the first person who was tested by it."
No one narrated this hadith from Sayyiduna Asim bin Adi (may Allah be pleased with him) except al-Sha'bi (may Allah have mercy on him), and Husayn (may Allah have mercy on him) is alone in narrating it from him.
