Ramadan is the holiest month in Islam which Muslims fast for 30 days and nights. Fasting or 'Sawm' as it is pronounced in Arabic, is the third pillar of Islam and is the duty of all Muslims who are of age and in good health to perform this act.

In the Qur'an it says:

"O you who believe! Fasting is prescribed for you as it was prescribed for those before you, that you may become Al-Muttaqun (The pious)".
- Qur'an chapter 2:183

The messenger of Allah, Prophet Muhammad (Peace be upon him) said:

"The gates of Hell are closed, the gates of Paradise are opened, and the devils are in chains. An angel calls out: 'O you who intend to do good deeds, have glad tidings. O you who intend to do evil, refrain, until Ramadan is completed."
