That the Messenger of Allah ﷺ said: "The earnings of the cupper is filth, the earnings of the fornicator (from harlotry) is filth, and the price of a dog is filth." [He said:] There are narrations on this topic from 'Umar, 'Ali, Ibn Mas'ud, Abu Masu'd, Jabir, Abu Hurairah, Ibn 'Abbas, Ibn 'Umar, and 'Abdullah bin Ja'far.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ كَسْبُ الْحَجَّامِ خَبِيثٌ وَمَهْرُ الْبَغِيِّ خَبِيثٌ وَثَمَنُ الْكَلْبِ خَبِيثٌ قَالَ وَفِي الْبَابِ عَنْ عُمَرَ وَعَلِيٍّ وَابْنِ مَسْعُودٍ وَأَبِي مَسْعُودٍ وَجَابِرٍ وَأَبِي هُرَيْرَةَ وَابْنِ عَبَّاسٍ وَابْنِ عُمَرَ وَعَبْدِ اللَّهِ بْنِ جَعْفَرٍ
