وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ، عَنْ مُحَمَّدِ بْنِ يُوسُفَ، قَالَ سَمِعْتُ السَّائِبَ بْنَ يَزِيدَ، يُحَدِّثُ عَنْ رَافِعِ بْنِ خَدِيجٍ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ "شَرُّ الْكَسْبِ مَهْرُ الْبَغِيِّ وَثَمَنُ الْكَلْبِ وَكَسْبُ الْحَجَّامِ "
