Yes, this is very clear in Islamic law: a hadith depicts Muhammad saying: “If a husband calls his wife to his bed [i.e. to have sexual relation] and she refuses and causes him to sleep in anger, the angels will curse her till morning” (Bukhari 4.54.460).

Another hadith attributes this to Muhammad: “By him in whose Hand lies my life, a woman can not carry out the right of her Lord, till she carries out the right of her husband. And if he asks her to surrender herself [to him for sexual intercourse] she should not refuse him even if she is on a camel’s saddle” (Ibn Majah 1854).

However, as far as I know Canada is not under Islamic law. Thus he should not have been found not guilty.
