Starting Saturday, Osama Al-Qasem and his wife, Manal Shurafa, started letting go of worldly concerns and focused on spiritual renewal. The Northampton couple weren’t alone. Muslims all over Bucks County are doing the same during Ramadan, the season during which the practice of prayer and sacrifice is intensified. The annual tradition, which lasts for 30 days, marks what Muslims believe was the time before the message of the Koran, Islam’s holy book, was revealed to the Prophet Mohammed.

Non-Muslims often view the holy month of Ramadan as another manifestation of an oppressive religion. Like many misinterpretations of Islam, this is way off the mark, for at its heart, Ramadan is imbued with thankfulness, joy, and compassion. Through fasting and self-denial, Muslims are reminded of all they have by temporarily living the life of those who have not.

As the director of “Out of Córdoba,” a documentary film about the religious coexistence of medieval Muslim Spain and Catholic Spain, I had the privilege of filming for several hours in the Great Mosque-Cathedral of Córdoba when it was empty of tourists.
