Amr bin Maymun narrates from his father that a brother of Bilal (may Allah be pleased with him) used to present himself as an Arab and claim to be one of them. He proposed marriage to an Arab woman, and those people said: "If Bilal comes, we will marry you." The narrator said: So Bilal came and said: "I am Bilal bin Rabah, and this is my brother. He is a bad man in character and religion. Now, if you wish, marry him, and if you wish, leave it." They said: "Whoever you are the brother of, we will certainly marry him." So they married him. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it; and narrations are also reported from this brother of Bilal.
