وَما آتَيتُم مِن رِبًا لِيَربُوَ في أَموالِ النّاسِ فَلا يَربو عِندَ اللَّهِ ۖ وَما آتَيتُم مِن زَكاةٍ تُريدونَ وَجهَ اللَّهِ فَأُولـٰئِكَ هُمُ المُضعِفونَ

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.
