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 ‏.‏

Yahya related to me from Malik from Ibn Shihab from Abu Bakr ibnAbd ar-Rahman ibn al-Harith ibn Hisham from Abu Masud al-Ansari thatthe Messenger of Allah, may Allah bless him and grant him peace,forbade the sale price of a dog, the earnings of a prostitute and theearnings of a fortune teller. By the earnings of a prostitutehe meant what a woman was given for fornication. The earnings of afortune teller were what he was given to tell a fortune. Malik said, "I disapprove of the price of a dog, whether it is ahunting dog or otherwise because the Messenger of Allah, may Allahbless him and grant him peace, forbade the price of a dog."
