Narrated Sa`id bin Jubair:

that he heard Ibn `Abbas saying, "If a man makes his wife unlawful for him, it does not mean that she is divorced." He added, "Indeed in the Messenger of Allah , you have a good example to follow."

حَدَّثَنِي الْحَسَنُ بْنُ صَبَّاحٍ، سَمِعَ الرَّبِيعَ بْنَ نَافِعٍ، حَدَّثَنَا مُعَاوِيَةُ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ يَعْلَى بْنِ حَكِيمٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، أَنَّهُ أَخْبَرَهُ أَنَّهُ، سَمِعَ ابْنَ عَبَّاسٍ، يَقُولُ إِذَا حَرَّمَ امْرَأَتَهُ لَيْسَ بِشَىْءٍ‏.‏ وَقَالَ ‏{‏لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ‏}
