Sayyiduna Wabisah bin Ma'bad al-Asadi (may Allah be pleased with him) narrates: I came to the Prophet (peace and blessings be upon him), intending to ask him about every kind of righteousness and sin. When I came to him, he was among some people who were sitting around him. I began stepping over them to get close to him, and one of them rebuked me and said: "O Wabisah! Keep away from the Messenger of Allah!" I said: "I want to get close to him." The Prophet (peace and blessings be upon him) said: "Leave Wabisah alone! O Wabisah, come close to me." The Prophet (peace and blessings be upon him) told me to come near, until I was in front of him. The Prophet (peace and blessings be upon him) said: "Will you ask me, or shall I tell you?" I said: "No! Rather, you tell me." The Prophet (peace and blessings be upon him) said: "You have come to ask about righteousness and sin." I said: "Yes!" Then the Prophet (peace and blessings be upon him) gathered his fingertips together and, tapping my chest with them, said: "Righteousness is that about which the soul is at peace and about which the heart is at peace; and sin is that which pricks in the soul and about which the soul wavers, whatever rulings people may give you."
Al-Tabarani recorded it, and Ahmad recorded it from that Companion in abridged form. The narrators of one of al-Tabarani's two chains are thiqat (trustworthy).
