Chapter on Usury (Riba)
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 27
وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: "لَيْسَ بَيْنَنَا وَ بَيْنَ أَهْلِ حَرْبِنَا رِبًا نَأْخُذُ مِنْهُمْ وَ لاَ نُعْطِيهِمْ".
The Messenger of Allah سبحانه وتعالى (may Allah سبحانه وتعالى bless him and his family) said: "There is no usury between us and the people with whom we are at war; we take from them, but we do not give to them."
