What is the ruling regarding a habitual drinker who engages in anal intercourse with his wife?

Performing intercourse with one's wife in her anus is a grave major sin, as the Prophet, peace and blessings be upon him, said: "Cursed is he who has intercourse with a woman in her anus." As for the wine drinker, his prayers are not accepted for forty mornings. If both matters combine, then he has committed two great sins: drinking wine and engaging in anal intercourse with his wife. However, his repentance is accepted if its conditions are met. The wife does not become unlawful to one who has committed these major sins.
