Yunus bin Maysarah narrates: I heard Sayyiduna Mu'awiyah bin Abi Sufyan (may Allah be pleased with him) say: I heard the Messenger of Allah (peace and blessings be upon him) say: "Goodness is a habit, and evil is obstinacy."
Ibn Bint Shurahbil, in his narration, added from the Prophet (peace and blessings be upon him): "And whomever Allah intends good for, He grants him understanding of the religion."
