What is the ruling on playing the role of a disbeliever in religious or other films, and is that considered disbelief? And what is the ruling on translating and dubbing programs and films made by disbelievers, which often contain disbelief?

Acting is permissible provided it is free from শরী'আ (Islamic law) prohibitions. This includes not uttering words of disbelief (kufr). The resolution of the Islamic Fiqh Council (Majma' al-Fiqh al-Islami) explicitly states this, as do the fatwas of the Permanent Committee (al-Lajnah ad-Da'imah), which hold that plays or acting that include words of disbelief are impermissible; rather, they are a reprehensible act (munkar). As for the ruling on one who utters a word of disbelief while acting, Shaykh Ibn 'Uthaymin was of the opinion that he does not commit kufr thereby, because he does not attribute kufr to himself; rather, he portrays himself as one who attributes it to himself, like someone who acts the part of a man who divorced his wife—the actor's wife is not divorced. However, he believed that acting the part of a disbeliever or a wicked person is not permissible for fear that it might affect the actor's heart or lead to him being criticized. In summary, uttering a word of disbelief or performing acts of disbelief, even in acting, must be avoided, and one must warn against it. As for translation, it is like writing from the outset: whatever is not permissible for a Muslim to write is not permissible for him to translate.
