Chapter on Usury (Riba)
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 27
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: "لَيْسَ بَيْنَ اَلْمُسْلِمِ وَ بَيْنَ اَلذِّمِّيِّ رِبًا وَ لاَ بَيْنَ اَلْمَرْأَةِ وَ بَيْنَ زَوْجِهَا رِبًا.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "There is no usury between a Muslim and a Dhimmi, nor between a woman and her husband."
