Ar Rum, 39 Ayah
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
Wa Mā 'Ātaytum Min Ribāan Liyarbuwā Fī 'Amwāli An-Nāsi Falā Yarbū `Inda Al-Lahi ۖ Wa Mā 'Ātaytum Min Zakāatin Turīdūna Wajha Al-Lahi Fa'ūlā'ika Humu Al-Muđ`ifūna
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.
