Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 2
وَ رَوَى حَمَّادٌ عَنِ اَلْحَلَبِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: أَنَّهُ سُئِلَ عَنْ رَجُلٍ قَالَ لاِمْرَأَتِهِ إِنْ تَزَوَّجْتُ عَلَيْكِ أَوْ بِتُّ عَنْكِ فَأَنْتِ طَالِقٌ فَقَالَ "إِنَّ رَسُولَ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ قَالَ "مَنْ شَرَطَ شَرْطاً سِوَى كِتَابِ اَللَّهِ عَزَّ وَ جَلَّ لَمْ يَجُزْ ذَلِكَ عَلَيْهِ وَ لاَ لَهُ" "، قَالَ وَ سُئِلَ عَنْ رَجُلٍ قَالَ كُلُّ اِمْرَأَةٍ أَتَزَوَّجُهَا مَا عَاشَتْ أُمِّي فَهِيَ طَالِقٌ فَقَالَ "لاَ طَلاَقَ إِلاَّ بَعْدَ نِكَاحٍ وَ لاَ عِتْقَ إِلاَّ بَعْدَ مِلْكٍ".
Hammad narrated from Al-Halabi that Abu Abdullah عليه السلام was asked about a man who said to his wife, "If I marry another woman over you or spend a night away from you, then you are divorced." Imam عليه السلام replied: "The Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) said: 'Whoever sets a condition outside of the Book of Allah سبحانه وتعالى, it is neither binding upon him nor for him.'" Imam عليه السلام was also asked about a man who said: "Any woman I marry while my mother is alive is divorced." Imam عليه السلام replied: "There is no divorce except after marriage, and no emancipation except after ownership."
