12. The Chapters on Business Transactions - كتاب التجارات
It was narrated fromHaram bin Munayyisah that :
his father asked the Prophet (ﷺ) about the earnings of a cupper and he forbade him from that. Then he mentioned his need and he said: "Spend it on feeding your she-camels that draw water."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَبَابَةُ بْنُ سَوَّارٍ، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، عَنْ حَرَامِ بْنِ مُحَيِّصَةَ، عَنْ أَبِيهِ، أَنَّهُ سَأَلَ النَّبِيَّ ـ صلى الله عليه وسلم ـ عَنْ كَسْبِ الْحَجَّامِ فَنَهَاهُ عَنْهُ فَذَكَرَ لَهُ الْحَاجَةَ فَقَالَ . " اعْلِفْهُ نَوَاضِحَكَ "
