Is it considered disbelief for a man to take his Christian wife to church or to give her something that helps her do so, while he knows that she is going to commit an act of disbelief or utter words of disbelief, based on the interpretation of the noble verse: {And do not cooperate in sin and aggression}?

The previous answer did not include the statement that a husband accompanying his Christian wife to church is not disbelief (kufr). Mere assistance in disbelief is not considered disbelief unless it is accompanied by contentment with it. The jurists have stipulated the prohibition of working in the construction or maintenance of churches, because it is assistance in sin. However, the Hanafis permitted this, as there is no sin in the act itself. And whoever's Islam is established with certainty, it is not permissible to rule him outside of it except with similar certainty.
