Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 3|Chapter 44
وَ سَأَلَ اَلْحَسَنُ اَلتَّفْلِيسِيُّ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: يَتَمَتَّعُ اَلرَّجُلُ مِنَ اَلْيَهُودِيَّةِ وَ اَلنَّصْرَانِيَّةِ قَالَ أَبُو اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ "يَتَمَتَّعُ مِنَ اَلْحُرَّةِ اَلْمُؤْمِنَةِ وَ هِيَ أَعْظَمُ حُرْمَةً مِنْهَا".
Al-Hasan Al-Taflisi asked Imam Ali ibn Musa Ar-Ridha عليه السلام: "Can a man engage in Mutah (temporary marriage) with a Jewish or Christian woman?" Abu Al-Hasan Al-Ridha عليه السلام replied: "He should engage in Mutah with a free believing woman, as she has greater sanctity than the others."
