It is that of which Allāh gives good tidings to His servants who believe and do righteous deeds. Say, [O Muḥammad], "I do not ask you for it [i.e., this message] any payment [but] only good will through [i.e., due to] kinship." And whoever commits a good deed - We will increase for him good therein. Indeed, Allāh is Forgiving and Appreciative.
