"One of the five pillars of Islam is prayer, and for almost all Muslims this means the five-times-daily practice of praise and petition. The action involves prostration toward Mecca as its most outward manifestation, but also includes words remarkably similar to our Judeo-Christian prayers. Asked to explain this practice of prayer, Muslims inevitably point to the real sense of corporate strength they derive from the idea that throughout the world fellow followers of Mohammed are praying the same words at the same time."
To Practice: Try this practice of praying in unison with Muslims and Christians at certain times during the day (sunrise and sunset being the most common).
