حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ مُحَمَّدٍ، - وَهُوَ ابْنُ زِيَادٍ - قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، وَرَأَى، رَجُلاً يَجُرُّ إِزَارَهُ فَجَعَلَ يَضْرِبُ الأَرْضَ بِرِجْلِهِ وَهُوَ أَمِيرٌ عَلَى الْبَحْرَيْنِ وَهُوَ يَقُولُ جَاءَ الأَمِيرُ جَاءَ الأَمِيرُ ‏.‏ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ إِنَّ اللَّهَ لاَ يَنْظُرُ إِلَى مَنْ يَجُرُّ إِزَارَهُ بَطَرًا ‏"‏ ‏.‏
