Fasting during the month of Ramadan is one of the five pillars of Islam. It is mandatory for every Muslim adult, male or female, who do not possess an allowable excuse to abstain. Fasting is a common practice in many religions, although there are differences in the nature and timing of the fasts. Fasting in Islam became an obligation on Sha'ban 10th in the second year after Hijra, and after the change in Qibla from Baitul Maqdas to Baitullah.
