أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ لَعَنَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْوَاصِلَةَ وَالْمُسْتَوْصِلَةَ وَالْوَاشِمَةَ وَالْمُوتَشِمَةَ ‏.‏ أَرْسَلَهُ الْوَلِيدُ بْنُ أَبِي هِشَامٍ ‏.‏
