Surah Ar-Rum · Ayah 39

وَمَآ ءَاتَيْتُم مِّن رِّبًۭا لِّيَرْبُوَا۟ فِىٓ أَمْوَٰلِ ٱلنَّاسِ فَلَا يَرْبُوا۟ عِندَ ٱللَّهِ ۖ وَمَآ ءَاتَيْتُم مِّن زَكَوٰةٍۢ تُرِيدُونَ وَجْهَ ٱللَّهِ فَأُو۟لَٰٓئِكَ هُمُ ٱلْمُضْعِفُونَ

Wa maaa aataitum mir ribal li yarbuwa feee amwaalin naasi falaa yarboo 'indal laahi wa maaa aataitum min zaakaatin tureedoona wajhal laahi fa ulaaa'ika humul mud'ifoon

And whatever you give for interest to increase within the wealth of people will not increase with Allah. But what you give in zakah, desiring the countenance of Allah - those are the multipliers.
