Yahya related to me from Malik that he had heard that
Abdullah ibn Masud said that there was nothing binding on someone who
said, "Every woman I marry is divorced," if he did not name a specific
tribe or woman.


Malik said, "That is the best of what I have
heard."


Malik said about a man saying to his wife, "You are
divorced, and every woman I marry is divorced," or that all his
property would be sadaqa if he did not do such-and-such, and he broke
his oath:
"As for his wives, it is divorce as he said, and as for his
statement, 'Every woman I marry is divorced', if he did not name a
specific woman, tribe, or land, or such, it is not binding on him and
he can marry as he wishes. As for his property, he gives a third of it
away as sadaqa."
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 ‏.‏
