Aboo Mas‘ood Al-Ansaaree(may Allah be pleased with him) narrated:
Allah's Messengerﷺ forbade availing oneself of the price of a dog, money earned by prostitution, and the earnings of a soothsayer.

Commentary :
Allah, Exalted is He, deemed lawful that which is good and ritually pure, and deemed unlawful that which is evil and ritually impure, with regards to food, beverages, earnings, trade, and so on. The Laws of Islam also urges Muslims to be gracious and deem themselves far above trivial and inferior aspirations.
In this hadeeth, Aboo Mas‘ood Al-Ansaaree(may Allah be pleased with him) narrated that the Prophet ﷺ forbade three things. First, the sale of dogs and availing oneself of the price. In fact, such earnings are declared unlawful, because it is prohibited to own and keep dogs, except those used for guarding livestock or crops. It was said that this is a general Laws of Islam ruling whether such a dogis trained for hunting or not, and whether or not it is allowable to keep such dog as per the laws of Islam. It was also said that guard and hunting dogs are excluded from this prohibition, because they are beneficial, as stated in the narration reported by Al-Daaraqutnee on the authority of Aboo Hurayrah (may Allah be pleased with him) reading: “except for a hunting dog.” Another relevant narration reported by Al-Tirmithee reads: “Except for dogs meant for hunting.” This means that he ﷺ forbade the price of dogs except for the ones the keeping of which are deemed allowable as per the laws of Islam given their benefit. It is also possible that the prohibition of taking and availing oneself of the dog’s price was prescribed in the early days of Islam and was later abrogated, and it was deemed allowable to use dogs for hunting animals and sell dogs just like other hunting animals.
The second is the money earned by a prostitute in return for engaging in illicit sexual intercourse with non-Mahram men. The Arabic word used in the hadeeth is ‘Mahr’ because such money is paid in a similar context of the dower in the case of lawful marriage.
In the pre-Islamic era, people used to force their slave-girls into prostitution to earn money, but Islam renounced this practice. Allah, Exalted is He, Says (what means): {And do not compel your slave girls to prostitution, if they desire chastity, to seek [thereby] the temporary interests of worldly life. And if someone should compel them, then indeed, Allah is [to them], after their compulsion, Forgiving and Merciful.} [Quran 24:33].
The third category is the earnings of a soothsayer in return for their prediction of the unseen.
A soothsayer refers to the one who claims to know the unseen, and informs people of his claims about unseen beings and future events. The reference here incorporates all those who claim such knowledge (to foresee the future), including astrologers, soothsayers who throw stones, and the like. The Arabic word used for the fees paid to a soothsayer is ‘Hulwaan’ literally denoting something sweet, because such money is taken for no real service rendered..
