Abu Dharr reported Allah's Messenger (ﷺ) as saying:
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 .
You would soon conquer Egypt and that is a land which is known (as the land of al-qirat). So when you conquer it, treat its inhabitants well. For there lies upon you the responsibility because of blood-tie or relationship of marriage (with them). And when you see two persons falling into dispute amongst themselves for the space of a brick, than get out of that. He (Abu Dharr) said: I saw Abd al-Rahman b. Shurahbil b. Hasana and his brother Rabi'a disputing with one another for the space of a brick. So I left that (land).
