Muwatta Malik, Book 31, Hadith 68 (USC-MSA) ⓘ

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."

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 ‏.‏
