30:39
وَمَآءَاتَيْتُممِّنرِّبًالِّيَرْبُوَا۟فِىٓأَمْوَٰلِٱلنَّاسِفَلَايَرْبُوا۟عِندَٱللَّهِ ۖوَمَآءَاتَيْتُممِّنزَكَوٰةٍتُرِيدُونَوَجْهَٱللَّهِفَأُو۟لَٰٓئِكَهُمُٱلْمُضْعِفُونَ٣٩
wamā ātaytum min riban liyarbuwā fī amwāli l-nāsi falā yarbū ʿinda l-lahi wamā ātaytum min zakatin turīdūna wajha l-lahi fa-ulāika humu l-muḍ'ʿifūna
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.(39)
