Surat Al-Hadid (The Iron) - الحديد

إِنَّ ٱلْمُصَّدِّقِينَ وَٱلْمُصَّدِّقَٰتِ وَأَقْرَضُوا۟ ٱللَّهَ قَرْضًا حَسَنًا يُضَٰعَفُ لَهُمْ وَلَهُمْ أَجْرٌ كَرِيمٌ ﴿١٨﴾

Surely (as for) the charitable men and the charitable women and (those who) set apart for Allah a goodly portion, it shall be doubled for them and they shall have a noble reward.
