Quran Ar-Rum 30:39
وَمَآ ءَاتَيۡتُم مِّن رِّبٗا لِّيَرۡبُوَاْ فِيٓ أَمۡوَٰلِ ٱلنَّاسِ فَلَا يَرۡبُواْ عِندَ ٱللَّهِۖ وَمَآ ءَاتَيۡتُم مِّن زَكَوٰةٖ تُرِيدُونَ وَجۡهَ ٱللَّهِ فَأُوْلَٰٓئِكَ هُمُ ٱلۡمُضۡعِفُونَ ٣٩
Translation
And whatever you give for interest [i.e., advantage] to increase within the wealth of people will not increase with Allāh. But what you give in zakāh, desiring the face [i.e., approval] of Allāh - those are the multipliers.
