Chapter on Usury (Riba)
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 27
وَ قَالَ عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ: "لَعَنَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ اَلرِّبَا وَ آكِلَهُ وَ مُؤْكِلَهُ وَ بَائِعَهُ وَ مُشْتَرِيَهُ وَ كَاتِبَهُ وَ شَاهِدَيْهِ".
Imam Ali ibn Abi Talib عليه السلام said: "The Messenger of Allah سبحانه وتعالى (may Allah سبحانه وتعالى bless him and his family) cursed usury, its consumer, its giver, its seller, its buyer, its recorder, and its two witnesses."
