حَدَّثَنِي مُحَمَّدُ بْنُ مُقَاتِلٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لَعَنَ اللَّهُ الْوَاصِلَةَ وَالْمُسْتَوْصِلَةَ، وَالْوَاشِمَةَ وَالْمُسْتَوْشِمَةَ " . قَالَ نَافِعٌ الْوَشْمُ فِي اللِّثَةِ.
