After the cartoon controversy, like predicted, Islam is even more on the menu so to speak. Swedish television acknowledged the Mawlid (birth) of the Prophet by showing the movie "The Message" (Al risala) and dedicating the whole evening to Islam.
The Islamic month Rabi-ul-Awwal (closest thing to April), is when the Prophet pbuh was said to have been born. Across the Muslim world it is customary to somehow acknowledge that day by either increasing in worship or singing spiritual songs dedicated to the Prophet Mohammad, either privately or collectively.
Mahabba Unlimited is organizing, I believe, it's second Mawlid in honour of the Prophet in London on the 30th of April, at the Wembley Conference Centre. Tickets can be purchased online.
