إِنَّ ٱلۡمُصَّدِّقِينَ وَٱلۡمُصَّدِّقَٰتِ وَأَقۡرَضُواْ ٱللَّهَ قَرۡضًا حَسَنٗا يُضَٰعَفُ لَهُمۡ وَلَهُمۡ أَجۡرٞ كَرِيمٞ١٨

inna l-muṣadiqīna wal-muṣadiqāti wa-aqraḍū l-laha qarḍan ḥasanan yuḍāʿafu lahum walahum ajrun karīmun

Indeed, the men who practice charity and the women who practice charity and [they who] have loaned Allāh a goodly loan - it will be multiplied for them, and they will have a noble reward.
