30:39
وَ مَآ ءَاتَيْ تُم مِّن رِّبًا لِّ يَرْبُوَا۟ فِىٓ أَمْوَٰلِ ٱل نَّاسِ فَ لَا يَرْبُوا۟ عِندَ ٱللَّهِ وَ مَآ ءَاتَيْ تُم مِّن زَكَوٰةٍ تُرِيدُ ونَ وَجْهَ ٱللَّهِ فَ أُو۟لَٰٓئِكَ هُمُ ٱلْ مُضْعِفُونَ
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.
