حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ بْنِ هِشَامٍ، عَنْ أَبِي مَسْعُودٍ الأَنْصَارِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ ثَمَنِ الْكَلْبِ وَمَهْرِ الْبَغِيِّ وَحُلْوَانِ الْكَاهِنِ ‏.‏ يَعْنِي بِمَهْرِ الْبَغِيِّ مَا تُعْطَاهُ الْمَرْأَةُ عَلَى الزِّنَا وَحُلْوَانُ الْكَاهِنِ رَشْوَتُهُ وَمَا يُعْطَى عَلَى أَنْ يَتَكَهَّنَ ‏.‏

Malik said, "It is the generally agreed on way of doing things among us that the meat of camels, cattle, sheep and so on is not to be bartered one for one, except like for like, weight for weight, from hand to hand. There is no harm in that. If it is not weighed, then it is estimated to be like for like from hand to hand." Malik said, "There is no harm in bartering the meat of fish for the meat of camels, cattle, and sheep and so on two or more for one, from hand to hand. If delayed terms enter the transaction however, there is no good in it." Malik said, "I think that poultry is different from the meat of cattle and fish. I see no harm in selling some of it for something different, more of one than another, from hand to hand. None of that is to be sold on delayed terms." Yahya related to me from Malik from Ibn Shihab from Abu Bakr ibn Abd ar-Rahman ibn al-Harith ibn Hisham from Abu Masud al-Ansari that the Messenger of Allah, may Allah bless him and grant him peace, forbade the sale price of a dog, the earnings of a prostitute and the earnings of a fortune teller. By the earnings of a prostitute he meant what a woman was given for fornication. The earnings of a fortune teller were what he was given to tell a fortune. Malik said, "I disapprove of the price of a dog, whether it is a hunting dog or otherwise because the Messenger of Allah, may Allah bless him and grant him peace, forbade the price of a dog
