وَمَا آتَيْتُم مِّن رِّبًا لِّيَرْبُوَ فِي أَمْوَالِ النَّاسِ فَلَا يَرْبُو عِندَ اللَّهِ وَمَا آتَيْتُم مِّن زَكَاةٍ تُرِيدُونَ وَجْهَ اللَّهِ فَأُولَئِكَ هُمُ الْمُضْعِفُونَ
What you give in usury in order that it may increase people’s wealth does not increase with Allah. But what you pay as zakat seeking Allah’s pleasure—it is they who will be given a manifold increase.
Agha Ali Puya Commentary
Commentary on Quran 30:39
[Pooya/Ali Commentary 30:39] Lending money on the condition that it will be repaid with a certain increase in the amount lent is called riba and collecting such an increase is forbidden in Islam. One has to show practical sympathy to someone in need by lending the monetary help needed without any such condition of enhanced repayment. The reward from Allah for such selfless service to fellow beings will be manifold-the return shall be multiplied many times the amount lent. Refer to the commentary of Baqarah: 275, and 277.
