the Messenger of Allah (may Allah's peace and blessings be upon him) prohibited the price …

There are many noble and good ways to seek sustenance and provision which Allah has blessed us with instead of the evil, corrupt and illegal ways. The good ways suffices the person so he is in no need of the evil ones. The huge harm resulting from the evil ways outweighs whatever benefit they may presumably involve. Islamic law prohibits all the evil ways of earning provision, including the three types mentioned in this Hadīth: 1. The price of selling a dog, as it is malevolent and impure (except for the trained dogs for three purposes: herding, hunting, and guarding, as mentioned in other verses of the Qur’an and Hadīth, etc). 2. The money a prostitute receives in return for practicing immorality, which destroys one's religion as well as the life of this world. 3. The money paid to people of misguidance and fraud, like soothsayers, diviners, and tricksters, who claim that they have knowledge of the unseen and have control over the created beings. They deceive people by their falsehood in order to take their wealth and devour it unlawfully. All of these ways are evil and prohibited in Islam and are impermissible to be used. One should not give anything in exchange for them, since Allah has provided noble, good and permissible ways to earn provisions that can substitute for these (and any) evil, corrupt and illegal ways.
