It was narrated that Yunus bin Maisarah bin Halbas said:
"I heard Mu'awiyah bin Abu Sufyan narrating that the Messenger of Allah said: "Goodness is a (natural) habit while evil is a stubbornness (constant prodding from Satan). When Allah wills good for a person, He causes him to understand the religion.'" (JA)
