Showing video tapes in which there are crosses in the mosque
Question

                We have some videotapes in the Islamic centre, and as part of our cultural program in the mosque we want to show a video tape which shows a play about the history of al-Quds (Jerusalem). It is free of music, and it shows the history from an Islamic point of view. But one of the actors wears a cross because he is playing the part of a priest. Is there anything wrong with showing this tape to the Muslims only, for it will inform the young people here, and the children and adults, about an important matter which is of concern to Muslims nowadays?
Praise be to Allah.Mosques 
          are built to be filled with the remembrance of Allaah and for the establishment 
          of salaah, and for the teaching of Islamic knowledge. Allaah has ordered 
          the mosques to be raised, i.e., venerated. Part of that veneration is 
          to protect them from everything that will compromise their sanctity, 
          such as vain talk and idle entertainment, and other kinds of falsehood 
          in word and deed. Showing plays in the mosque, even though it is for 
          an Islamic purpose, does not befit the sanctity of the mosque, because 
          these films are based on acting and image-making; these are the two 
          main features of all kinds of entertainment, no matter what kind they 
          are or what their aims are. The Muslims should do without them by teaching 
          instead; it is possible and is easy to teach instead without them. And 
          hardly any plays are free of some kind of munkar (evil; reprehensible 
          action), to a greater or lesser extent. 
 Acting 
          is more obviously doubtful. If these films have to be shown, then it 
          should be done somewhere other than the mosque, out of respect for its 
          sanctity, and so as to avoid making any kind of connection between the 
          mosque and entertainment.
