Not upon you, [O Muḥammad], is [responsibility for] their guidance, but Allāh guides whom He wills. And whatever good you [believers] spend is for yourselves, and you do not spend except seeking the face [i.e., approval] of Allāh. And whatever you spend of good - it will be fully repaid to you, and you will not be wronged.
[Charity is] for the poor who have been restricted for the cause of Allāh, unable to move about in the land. An ignorant [person] would think them self-sufficient because of their restraint, but you will know them by their [characteristic] sign. They do not ask people persistently [or at all]. And whatever you spend of good - indeed, Allāh is Knowing of it.
