According to the Hanafi text, Fatawa Qadhikhan, according to Imam Abi Hanifah (rahimahullah) there is no hadd for paying a woman for the purpose of committing zina with her:
ولو استأجر امرأة ليزني بها فزنى بها, لا يحدّ في قول أبي حنيفة رحمه الله تعالى
“If he paid a woman to do zina with her, so he did zina with her, there is no hadd in the saying of Abi Hanifah may Allah Most High have mercy on him” (Fatawa Qadhikhan v.3 p.382):
However, this position of Imam Abi Hanifah does not mean that he considered such an act as permissible, only that there is no hadd (statutory punishment) for it according to his opinion and ijtihad. Nevertheless, this is his individual position, but the position of the Hanafi madhhab, upon which is the fatwa of the madhhab, is that there is a hadd to be enforced in such a scenario.
