Allah did not create man so that he could have fun. The aim of creation was for mankind to be put to the test through hardship and prayer. An Islamic regime must be serious in every field. There are no jokes in Islam. There is no humour in Islam. There is no fun in Islam. There can be no fun or joy in whatever is serious.

Ayatollah Ruholla Khomeini, radio sermon, 1979.

Consider what the effect on the Islamic world would have been had the Monty Python film Life of Brian, with the lead character playing the Prophet rather than the Saviour, featured on the marquees. As Ibn Warraq facetiously asked in an article for City Journal (vol. 18. no. 1), “can we look forward, someday, to a Life of Mo?” Monty Python and The Holy Grail would not have fared much better either, though the Holy Hand Grenade might have struck a chord. Or how about Mel Brooks’ History of the World Part I, with its hilarious skit of Moses dropping one of the tablets, reducing the fifteen commandments to ten, had a similar disaster befallen one of the scrolls of the Koran.

Al Shabaab is an example of an organization that doesn't believe in fun unless fun is whipping women.  An Al Qaeda proxy in Somalia Al Shabaab has banned movies, musical ringtones, dancing at wedding ceremonies and playing or watching soccer.  They whip women who wear bras claiming that bras violate Islam as they are 'deceptive'.  They also whip any man caught without a beard.  One Somali said "You just find yourself being whipped by a masked man as soon as leave your house."  Al Shabaab has banned televisions:

Using loudspeakers mounted on vehicles, al-Shabaab banned the people of Barawe from watching television, saying it harms their Islamic principles, and ordered them to turn in their televisions and satellite dishes to al-Shabaab officials.  Residents who keep televisions are accused of being infidels. 

On December 23, 2012, in response to a question posed by a Saudi youth, Saudi sheikh Suleiman Al-'Alwan  said that soccer was a form of heresy: "Soccer is a Masonic game meant to distance Muslims from their religion and faith, and most of the public that follows [soccer games] is loyal to the infidels." Al-'Alwan called soccer players criminals and infidels: "[When] a man watches a [soccer] game, God forbid, he is watching deviant criminals and sinful infidels, even if they are Muslims." He added: "There is a serious problem with [soccer] games, which is the refereeing, which follows manmade laws, not Allah's laws."[3]  Obviously not all Muslim soccer players agree with the Saudi Sheikh.
