حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، وَعُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا أَبِي، سَمِعْتُ حَرْمَلَةَ الْمِصْرِيَّ، يُحَدِّثُ عَنْ عَبْدِ الرَّحْمَنِ بْنِ شُمَاسَةَ، عَنْ أَبِي بَصْرَةَ، عَنْ أَبِي، ذَرٍّ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّكُمْ سَتَفْتَحُونَ مِصْرَ وَهِيَ أَرْضٌ يُسَمَّى فِيهَا الْقِيرَاطُ فَإِذَا فَتَحْتُمُوهَا فَأَحْسِنُوا إِلَى أَهْلِهَا فَإِنَّ لَهُمْ ذِمَّةً وَرَحِمًا ‏"‏ ‏.‏ أَوْ قَالَ ‏"‏ ذِمَّةً وَصِهْرًا فَإِذَا رَأَيْتَ رَجُلَيْنِ يَخْتَصِمَانِ فِيهَا فِي مَوْضِعِ لَبِنَةٍ فَاخْرُجْ مِنْهَا ‏"‏ ‏.‏ قَالَ فَرَأَيْتُ عَبْدَ الرَّحْمَنِ بْنَ شُرَحْبِيلَ بْنِ حَسَنَةَ وَأَخَاهُ رَبِيعَةَ يَخْتَصِمَانِ فِي مَوْضِعِ لَبِنَةٍ فَخَرَجْتُ مِنْهَا ‏.‏
