The holy month of Ramadan is upon us, and over 1.6 billion Muslims worldwide will observe fasting for the next 30 days. This marks the ninth month in the lunar calendar and according to scholars, Ramadan is the month in which Quran, the Islamic holy text, was first revealed.

It is understood that the crescent moon will be sighted in countries like the United Arab Emirates and Saudi Arabia a day ahead of the South Asian countries, which also have a high Muslim population. However, the holy month of Ramadan unites all practising Muslims who fast from dawn to dusk, pray and give alms to the less fortunate.
