Sawm (Fasting)
Fasting is obligatory for every Muslim adult, male or female, for the entire lunar month of Ramadhan every year. The fast lasts from the true dawn until dusk.
During the fast one has to abstain from eating, drinking, smoking and some other actions.
In this regard the Qur’an says:
“O ye who believe! Fasting is prescribed to you, as it was prescribed to those before you, that ye may exercise self-restraint”. (2:183)
“So every one of you who witnesses this month should fast in it”. (2:185)
