إِنَّ ٱلۡمُصَّدِّقِينَ وَٱلۡمُصَّدِّقَٰتِ وَأَقۡرَضُواْ ٱللَّهَ قَرۡضًا حَسَنٗا يُضَٰعَفُ لَهُمۡ وَلَهُمۡ أَجۡرٞ كَرِيمٞ
English translation: Indeed the men who give charity and the women who give charity and who lend (to) Allah a loan goodly it will be multiplied for them and for them (is) a reward noble
