[Machine] About the Prophet ﷺ , there are three things, all of which are sinful: he mentioned the earnings of cupping, the dowry of an unlawful marriage, and the price of a dog except for a guard dog. Also, Al-Walid and Al-Muthanna are considered weak.
عَنِ النَّبِيِّ ﷺ ثَلَاثٌ كُلُّهُنَّ سُحْتٌ فَذَكَرَ كَسْبَ الْحَجَّامِ وَمَهْرَ الْبَغِيِّ وَثَمَنَ الْكَلْبِ إِلَّا كَلْبًا ضَارِيًا وَالْوَلِيدُ وَالْمُثَنَّى ضَعِيفَانِ
