You would soon conquer a land where people are in the habit of using foul language. They have a right of kinship upon you. And when you see two persons fighting for the space of a brick, then get out of that. He (Abu Dharr) then happened to pass by Rabila and 'Abd al-Rahman, the two sons of Shurahbil b. Hasana, and they had been disputing for the space of a brick. So he left the land.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّكُمْ سَتَفْتَحُونَ أَرْضًا يُذْكَرُ فِيهَا الْقِيرَاطُ فَاسْتَوْصُوا بِأَهْلِهَا خَيْرًا فَإِنَّ لَهُمْ ذِمَّةً وَرَحِمًا فَإِذَا رَأَيْتُمْ رَجُلَيْنِ يَقْتَتِلاَنِ فِي مَوْضِعِ لَبِنَةٍ فَاخْرُجْ مِنْهَا قَالَ فَمَرَّ بِرَبِيعَةَ وَعَبْدِ الرَّحْمَنِ ابْنَىْ شُرَحْبِيلَ بْنِ حَسَنَةَ يَتَنَازَعَانِ فِي مَوْضِعِ لَبِنَةٍ فَخَرَجَ 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). (Using translation from Muslim 2543b)  

قَالَ رَسُولُ اللهِ ﷺ 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 ابْنِ حَسَنَةَ وَأَخَاهُ رَبِيعَةَ يَخْتَصِمَانِ فِي مَوْضِعِ لَبِنَةٍ فَخَرَجْتُ مِنْهَا

"إِنَّكم ستفتحون مصرا، وهى أرضٌ يُسَمَّى فيها القيراطُ. فإذا فَتَحْتُمُوها فاستوصوا بأَهلِهَا خيرًا، وفى لفظ "فأَحسنوا إِلى أهلها، فإِن لهم ذمَّة وَرَحِمًا، فإِذا رأيت رجلين يختصمان في موضع لَبِنَة فاخرجُ منها".
