وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ ‏"‏ لَنْ يَبْرَحَ هَذَا الدِّينُ قَائِمًا يُقَاتِلُ عَلَيْهِ عِصَابَةٌ مِنَ الْمُسْلِمِينَ حَتَّى تَقُومَ السَّاعَةُ ‏"‏ ‏.‏
