فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ ۗ وَيَسْـَٔلُونَكَ عَنِ ٱلْيَتَٰمَىٰ ۖ قُلْ إِصْلَاحٌۭ لَّهُمْ خَيْرٌۭ ۖ وَإِن تُخَالِطُوهُمْ فَإِخْوَٰنُكُمْ ۚ وَٱللَّهُ يَعْلَمُ ٱلْمُفْسِدَ مِنَ ٱلْمُصْلِحِ ۚ وَلَوْ شَآءَ ٱللَّهُ لَأَعْنَتَكُمْ ۚ إِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌۭ
Upon the world and the Hereafter. And they question thee concerning orphans. Say: To improve their lot is best. And if ye mingle your affairs with theirs, then (they are) your brothers. Allah knoweth him who spoileth from him who improveth. Had Allah willed He could have overburdened you. Allah is Mighty, Wise.
