 ١٦ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ مَحْبُوبٍ عَنْ ضُرَيْسٍ الْكُنَاسِيِّ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ السَّلام) مِنْ أَيْنَ دَخَلَ عَلَى النَّاسِ الزِّنَا قُلْتُ لا أَدْرِي جُعِلْتُ فِدَاكَ قَالَ مِنْ قِبَلِ خُمُسِنَا أَهْلَ الْبَيْتِ إِلا شِيعَتَنَا الاطْيَبِينَ فَإِنَّهُ مُحَلَّلٌ لَهُمْ لِمِيلادِهِمْ.
 16. Ali ibn Ibrahim has narrated from his father from ibn Mahbub from Durays al-Kunnas who has said the following. “Abu ‘Abdallah  said, “Why people get the course of adultery?” I said, “I do not know, May Allah take my soul in service for your cause.” He said, “It is because of not paying our al-Khums (one fifth religious dues) except our pure Shi‘a. It helps cleans their birth.”
