حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَبَابَةُ بْنُ سَوَّارٍ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، عَنْ حَرَامِ بْنِ مُحَيِّصَةَ، عَنْ أَبِيهِ، أَنَّهُ سَأَلَ النَّبِيَّ ـ صلى الله عليه وسلم ـ عَنْ كَسْبِ الْحَجَّامِ فَنَهَاهُ عَنْهُ فَذَكَرَ لَهُ الْحَاجَةَ فَقَالَ ‏"‏ اعْلِفْهُ نَوَاضِحَكَ ‏"‏ ‏.‏
