Translation for 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
Whatever loans you give, ˹only˺ seeking interest at the expense of people’s wealth1 will not increase with Allah. But whatever charity you give, ˹only˺ seeking the pleasure of Allah—it is they whose reward will be multiplied.
