[Machine] He heard the Messenger of Allah ﷺ say, "The worst of earnings is the earnings of a bloodletter, the price of a dog, and the dowry of a prostitute." Abdullah ibn Abdullah disagreed with him.  

الكبرى للنسائي:٤٦٦٥ – حَدَّثَنَا الْحُسَيْنُ بْنُ حُرَيْثٍ أَخْبَرَنَا الْفَضْلُ بْنُ مُوسَى عَنْ جُعَيْدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ يَزِيدَ بْنِ خُصَيْفَةَ عَنِ السَّائِبِ بْنِ يَزِيدَ عَنْ رَافِعِ بْنِ خَدِيجٍ

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ «شَرُّ الْكَسْبِ كَسْبُ الْحَجَّامِ وَثَمَنُ الْكَلْبِ وَمَهْرُ الْبَغِيِّ» خَالَفَهُ عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللهِ
