If a Muslim knows that contracted AIDS, is it permissible on him to engage in sexual relations with his wife? Is it obligatory for him to inform his wife about it?
Answer
If he knows that the virus can infect her through sexual relations, it is not permissible for him at all. Similarly [it is obligatory on him to refrain from sex] if there exists a considerable level of likelihood [of infection], except in the case where the wife knows about it and agrees to it.
