Qur'an 30:39

وَمَآ ءَاتَيْتُم مِّن رِّبًا لِّيَرْبُوَا۟ فِىٓ أَمْوَٰلِ ٱلنَّاسِ فَلَا يَرْبُوا۟ عِندَ ٱللَّهِ ۖ وَمَآ ءَاتَيْتُم مِّن زَكَوٰةٍ تُرِيدُونَ وَجْهَ ٱللَّهِ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُضْعِفُونَ

That which ye give in usury in order that it may increase on (other) people's property hath no increase with Allah; but that which ye give in charity, seeking Allah's Countenance, hath increase manifold.
