٥- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ كَسْبِ الْحَجَّامِ فَقَالَ لا بَأْسَ بِهِ قُلْتُ أَجْرُ التُّيُوسِ قَالَ إِنْ كَانَتِ الْعَرَبُ لَتَعَايَرُ بِهِ وَلا بَأْسَ. 
5. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ‘Isma’il from al-Fadl ibn Shadhan from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “This is concerning my question before abu ‘Abd Allah , about the legal status of the income from cupping. He (the Imam) replied, There is no offense in it.’ I then asked about income from he-goat for goat-grooming. He (the Imam) replied, ’Even though Arab people consider it scornful, there is no offense in receiving such income.’”
