What is the ruling on electronically circulated jokes that deal with the Islamic religion, such as: "A hen hung a picture of a fried egg… Why? This is a picture of her martyred brother," and "A Lebanese imam recited Al-Fatihah in prayer… And when the women said 'Ameen,' he said: 'May this voice be my sacrifice [or how beautiful is this voice], I will recite Al-Fatihah again,' and 'A fox met a rooster that was on top of a wall and said to him: 'Come down, let us pray in congregation,' and other jokes that involve angels?

All that was mentioned in the question is considered mockery and ridicule of the Islamic religion, its sanctities, and its teachings. If the perpetrator is a Muslim and did so out of mockery, then he has committed an act of disbelief (kufr) that expels him from the fold of Islam, as Allah the Almighty says: "And if you ask them, they will surely say, 'We were only conversing and playing.' Say, 'Is it in Allah and His verses and His Messenger that you were mocking?' Make no excuse; you have disbelieved after your belief." Mocking the religion is among the gravest of major sins. If the publisher is an enemy of Islam, then there is no surprise, for their enmity will persist until Muslims abandon their religion, as Allah the Almighty says: "And never will the Jews or the Christians approve of you until you follow their religion." It is the Muslim's duty to defend his faith and his sanctities.
