Ramadan 2009 takes place from August 22-September 20th. Some Christian ministries have put out guides to praying for Muslims during this time.
Religious fasts and holidays are times to not only observe tradition, but to evalute one's commitment; to ask oneself, "Is this really my faith? Is this what I want to adhere to?"
From The 30-Days Prayer Network:
The name Ramadan is derived from the Arabic word ramida or ar-ramad, denoting intense scorching heat and dryness, especially the ground. From the same word there is ramdaa, meaning ’sunbaked sand’ and the famous proverb Kal Mustajeer minar ramadaa binnar – to jump out of the frying pan into the fire. Some say it is so called because Ramadan scorches out the sins with good deeds, as the sun burns the ground.
Although it's a little late to order prayer booklets, the following links will take you to sites that give a prayer focus for each day during Ramadan.
