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 (PBUH) as saying: 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. Translation Not Available
