Sayyiduna Wabisah bin Ma'bad (may Allah be pleased with him), a Companion of the Prophet (peace and blessings be upon him), narrates: I came to the Prophet (peace and blessings be upon him) to ask about righteousness and sin. He (peace and blessings be upon him) said: Have you come to ask about righteousness and sin? Sayyiduna Wabisah (may Allah be pleased with him) said: By the One who sent you (peace and blessings be upon him) with the truth, I have not come to you to ask about anything other than this. The Prophet (peace and blessings be upon him) said: "Righteousness is that for which your heart is at ease, whatever ruling people may give you about it."
Ahmad and al-Bazzar recorded it; its chain contains a narrator, Abu Abdullah al-Sulami. Al-Bazzar's wording is: al-Asadi narrated it from Sayyiduna Wabisah (may Allah be pleased with him), and Mu'awiyah bin Salih narrated it from him. (Allamah al-Haythami says:) I have not seen anyone who has written a biography of him.
