أَخْبَرَنَا عَلِيُّ بْنُ الْحُسَيْنِ، قَالَ حَدَّثَنَا أُمَيَّةُ، عَنْ شُعْبَةَ، عَنْ حَبِيبٍ، قَالَ حَدَّثَنِي أَبُو الْعَبَّاسِ، - وَكَانَ رَجُلاً مِنْ أَهْلِ الشَّامِ وَكَانَ شَاعِرًا وَكَانَ صَدُوقًا - عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم وَسَاقَ الْحَدِيثَ ‏.‏
