Muslims fast the month of Ramadan because Allah has commanded them to do so. Therefore, Muslims worship Allah through fasting which is beloved to Allah and which He has enjoined upon us.

The age at which parents should start to teach their children to fast is the age at which they are able to fast. Some scholars have defined this as being ten years of age.

Allah singled out fasting for Himself from all other good deeds, because of its honoured status before Him, because He loves it and because it is a demonstration of sincerity towards Him, as it is a secret between a person and his Lord, which no one can see except Allah.

The fast of one who does not pray is not valid and is not accepted, because the one who does not pray is a disbeliever and an apostate.

Fasting is compulsory on a person if he fulfils five conditions: 1- He is a Muslim, 2- He is accountable (mukallaf), 3- He is able to fast, 4- He is settled (not travelling), and 5- There are no impediments to fasting.
