13ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ صَبَّاحِ بْنِ سَيَابَةَ قَالَ كُنْتُ عِنْدَ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) فَقَالَ لَهُ مُحَمَّدُ بْنُ عَبْدَةَ يَزْنِي الزَّانِي وَهُوَ مُؤْمِنٌ قَالَ لا إِذَا كَانَ عَلَى بَطْنِهَا سُلِبَ الإيمَانُ مِنْهُ فَإِذَا قَامَ رُدَّ عَلَيْهِ قُلْتُ فَإِنَّهُ أَرَادَ أَنْ يَعُودَ قَالَ مَا أَكْثَرَ مَا يَهُمُّ أَنْ يَعُودَ ثُمَّ لا يَعُودُ.
13. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu’awiyah ibn ‘Ammar from Sabah ibn Siyabah who has said the following: “Once I was in the presence of Abu ‘Abdillah and Muhammad ibn ‘Abdahu said, ‘A fornicator fornicates. Is he still a believer?’ The Imam said, ‘As long as he is on her belly he is not a believer and when he stands up, belief is returned to him.’ I then asked, ‘What if one intends to repeat?’ The Imam said, ‘How many are they who intend but do not repeat!”’
