وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ، كَانَ يَقُولُ إِذَا لَمْ يَجِدِ الرَّجُلُ مَا يُنْفِقُ عَلَى امْرَأَتِهِ فُرِّقَ بَيْنَهُمَا ‏.‏ قَالَ مَالِكٌ وَعَلَى ذَلِكَ أَدْرَكْتُ أَهْلَ الْعِلْمِ بِبَلَدِنَا ‏.‏

Yahya related to me fromMalik that he had heard that Said ibn al-Musayyab said, "If a man doesnot find the means to spend on his wife, they are to be separated . " Malik said, "That is what I saw the people of knowledge inour city doing." 29.30 Idda of Widows when Pregnant Translation Not Available
