حَدَّثَنِي أَبُو الطَّاهِرِ، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي حَرْمَلَةُ، ح وَحَدَّثَنِي هَارُونُ بْنُ، سَعِيدٍ الأَيْلِيُّ حَدَّثَنَا ابْنُ وَهْبٍ، حَدَّثَنِي حَرْمَلَةُ، - وَهُوَ ابْنُ عِمْرَانَ التُّجِيبِيُّ - عَنْ عَبْدِ الرَّحْمَنِ، بْنِ شُمَاسَةَ الْمَهْرِيِّ قَالَ سَمِعْتُ أَبَا ذَرٍّ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ 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 ‏.‏

Abu Dharr reported Allah's Messenger (ﷺ) as saying

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).
