وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ، كَانَ يَقُولُ فِيمَنْ قَالَ كُلُّ امْرَأَةٍ أَنْكِحُهَا فَهِيَ طَالِقٌ إِنَّهُ إِذَا لَمْ يُسَمِّ قَبِيلَةً أَوِ امْرَأَةً بِعَيْنِهَا فَلاَ شَىْءَ عَلَيْهِ ‏.‏ قَالَ مَالِكٌ وَهَذَا أَحْسَنُ مَا سَمِعْتُ ‏.‏ قَالَ مَالِكٌ فِي الرَّجُلِ يَقُولُ لاِمْرَأَتِهِ أَنْتِ الطَّلاَقُ وَكُلُّ امْرَأَةٍ أَنْكِحُهَا فَهِيَ طَالِقٌ وَمَالُهُ صَدَقَةٌ إِنْ لَمْ يَفْعَلْ كَذَا وَكَذَا فَحَنِثَ قَالَ أَمَّا نِسَاؤُهُ فَطَلاَقٌ كَمَا قَالَ وَأَمَّا قَوْلُهُ كُلُّ امْرَأَةٍ أَنْكِحُهَا فَهِيَ طَالِقٌ فَإِنَّهُ إِذَا لَمْ يُسَمِّ امْرَأَةً بِعَيْنِهَا أَوْ قَبِيلَةً أَوْ أَرْضًا أَوْ نَحْوَ هَذَا فَلَيْسَ يَلْزَمُهُ ذَلِكَ وَلْيَتَزَوَّجْ مَا شَاءَ وَأَمَّا مَالُهُ فَلْيَتَصَدَّقْ بِثُلُثِهِ ‏.‏

Yahya related to me from Malik that he had heard thatAbdullah ibn Masud said that there was nothing binding on someone whosaid, "Every woman I marry is divorced," if he did not name a specifictribe or woman. Malik said, "That is the best of what I haveheard." Malik said about a man saying to his wife, "You aredivorced, and every woman I marry is divorced," or that all hisproperty would be sadaqa if he did not do such-and-such, and he brokehis oath: "As for his wives, it is divorce as he said, and as for hisstatement, 'Every woman I marry is divorced', if he did not name aspecific woman, tribe, or land, or such, it is not binding on him andhe can marry as he wishes. As for his property, he gives a third of itaway as sadaqa." Translation Not Available
