The religion of Islam is founded on five pillars - Shahadah (declaration of faith); Salah (the five daily obligatory prayers); Zakah (obligatory charity); Siyam (fasting during the month of Ramadhan); and Hajj (pilgrimage to Makkah at least once in his/her lifetime for those who are physically and financially able to do so).
A month-long fast
Ramadhan is the ninth month in the Islamic Hijri calendar, and has been designated as that for the month-long fast of Islam. The Islamic calendar is a lunar calendar and 11-12 days shorter than the Gregorian calendar.
This results in the duration of the months being either 29 to 30 days, depending on the sighting of the New Moon ie one month ends and another begins when the New Moon is sighted. It was expected that Ramadhan 2010 would commenced last Thursday August 12, Inshallah (God Willing).
The significance of the month of Ramadhan is contained in chapter two verse 185 of the Holy Qur'an: "Ramadhan is the (month) in which was sent down The Qur'an, as a guide to mankind, also clear (signs) for guidance and judgement (between right and wrong). So every one of you who is present (at his home) during that month should spend it in fasting."
Muhammad's mandate
It was during the month of Ramadhan that the first revelations of the Qur'an were given to the unlettered Prophet of Islam, Muhammad (uwbp). The Prophet (uwbp) used to retire to a cave in the side of Mount Hira, some three miles north of the city of Makkah, where he spent the time in prayer and contemplation.
It was here that in his fortieth year he was visited during the month of Ramadhan by "a dazzling vision of beauty and light" (the angel Gabriel) who spoke the word, "Iqra!" (Read! Proclaim! Recite!) and who made clear to Muhammad (uwbp) that he would be the instrument through which God's revelations would be delivered to mankind.
Today, for the world's one billion plus followers of Islam, the Holy Qur'an remains "a fountain of mercy and wisdom, a warning to the heedless, a guide to the erring, and an assurance to those in doubt, a solace to the suffering, a hope to those in despair, and a mercy to mankind."
