To this world and the Hereafter. And they ask you about orphans. Say, "Improvement for them is best. And if you mix your affairs with theirs - they are your brothers. And Allāh knows the corrupter from the amender. And if Allāh had willed, He could have put you in difficulty. Indeed, Allāh is Exalted in Might and Wise."
