Chapter 86 | Marriage with Taxpayers and Pagans of Whom Certain Ones Become Muslims and other do not Become Muslims or all of them Become Muslims
2- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ عَبْدِ اللهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللهِ قَالَ إِذَا أَسْلَمَتِ امْرَأَةٌ وَزَوْجُهَا عَلَى غَيْرِ الإسْلامِ فُرِّقَ بَيْنَهُمَا قَالَ وَسَأَلْتُهُ عَنْ رَجُلٍ هَاجَرَ وَتَرَكَ امْرَأَتَهُ فِي الْمُشْرِكِينَ ثُمَّ لَحِقَتْ بَعْدَ ذَلِكَ بِهِ أَيُمْسِكُهَا بِالنِّكَاحِ الأوَّلِ أَوْ تَنْقَطِعُ عِصْمَتُهَا قَالَ بَلْ يُمْسِكُهَا وَهِيَ امْرَأَتُهُ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from ‘Abd Allah ibn Sinan who has said the following: “Abu ’Abd Allah , has said, ‘If a woman becomes Muslim and she is married in a way that is an un-Islamic way, they must be separated.’ I then asked him (the Imam) about the case of a man who migrates and leaves his wife among the pagans, then she joins him; if he can keep her with the first marriage or that her safety is cut off. He (the Imam) said, ‘He can keep her; she is his wife.’”
