What should I do about falling into the abomination of adultery with a prostitute, due to not satisfying sexual desire because of the wife's frigidity?

Adultery is one of the gravest sins after polytheism (shirk) with Allah. Its reprehensibility increases if committed by a married person, and Allah has ordained stoning to death as its punishment. A wife's refusal to share her husband's bed is a major sin that incurs a curse, unless there is a legitimate Sharia-compliant excuse, and by doing so, she is considered rebellious (nashiz). However, the wife's action is not a justification for adultery.

Whoever has fallen into this heinous act must offer sincere repentance and deep remorse, coupled with abundant righteous deeds that expiate sins. They must also be keen on concealing their sin and not mentioning what happened to anyone. Allah has promised to accept the repentance of those who repent.
