أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا أَبُو دَاوُدَ، عَنْ شُعْبَةَ، قَالَ أَخْبَرَنِي مَنْصُورٌ، قَالَ سَمِعْتُ رِبْعِيًّا، يُحَدِّثُ عَنْ أَبِي بَكْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا أَشَارَ الْمُسْلِمُ عَلَى أَخِيهِ الْمُسْلِمِ بِالسِّلاَحِ فَهُمَا عَلَى جُرُفِ جَهَنَّمَ فَإِذَا قَتَلَهُ خَرَّا جَمِيعًا فِيهَا " .
