Zinaa for money

A man hired a woman, by giving her ujra, to have sexual intercourse with him. Then he committed Zinaa with her. According to Abu Hanifah there is no hadd upon either of them. 

Abu Yusuf, Muhammad, and al-Shaafi'i (may Allaah have mercy on them) correctly said: They both will be subjected to the hadd punishment because they indulged in Zinaa. 

No one has understood Abu Hanifah's incorrect verdict on the matter to mean that he saw it to be permissible. 

He just didn't consider it to be Zinaa which required the hadd punishment. He made a mistake in his Qiyaas. 

No Muslim could declare the act of having sexual intercourse in return for money as permissible.
