Can a woman deny to have sex with her husband if he comes home having consumed alcohol?

All perfect praise be to Allaah, The Lord of the Worlds.  I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

It is incumbent upon the wife to be obedient to her husband in all cases within reasonable limits and especially if he calls her to bed – to which she has to respond, as in some narrations which were reported in this regard. The Prophet , said: “If a husband calls his wife to bed (to have sexual intercourse with her) and she refuses, and he spends the night angry with her, the angels would curse her until she gets up in the morning.” [Al-Bukhari and Muslim] The wife's refusal to satisfy her husband's desires could cause him to seek satisfaction by committing adultery.

However, this woman has to explain the dangers of drinking alcohol to her husband and advise him regarding his religion and worldly matters, especially regarding any children they may have together.

Allaah Knows best.
