Ramadan Kareem..

Ramadan is the 9th month of the Islamic calendar. The term Ramadan literally means scorching in Arabic. It was established as a Holy Month for Muslims after the Quran was revealed to the Prophet Muhammad in 610 CE on the occasion known as Laylat al-Qadr, frequently translated as "the Night of Power.
Observance of Ramadan is mandated in the Quran, Surah 2, Ayah 185:

“The month of Ramadhan [is that] in which was revealed the Qur'an, guidance for the people and clear proofs of guidance and criterion. So whoever sights [the new moon of] the month, let him fast it; and whoever is ill or on a journey - then an equal number of other days. Allah intends for you ease and does not intend for you hardship and [wants] for you to complete the period and to glorify Allah for that [to] which He has guided you; and perhaps you will be grateful.”In general, the practices of Ramadan are meant to purify oneself from thoughts and deeds which are counter to Islam. By removing material desires, one is able to focus fully on devotion and service to God. Many Muslims go beyond the physical ritual of fasting and attempt to purge themselves of impure thoughts and motivations such as anger, cursing, and greed.
During the month of Ramadan, most Muslims fast from dawn to sunset with no food or water. Before sunrise many Muslims have the Suhur or predawn meal. At sunset families and friends gather for Iftar which is the meal eaten by Muslims to break the fast. Many Muslims begin the meal by eating dates as the Prophet used to do.
This ritual fast known as, Sawm, is one of the five pillars of Islam, and requires that individuals abstain from eating, drinking, smoking and sexual intercourse.
