The fast
:
In the second year of the hijrah, fasting was made obligatory. Allah revealed, 'O you who believe, the fast is prescribed for you as it was prescribed for those before you - perhaps you will be God-fearing.' (2: 183)
He says, 'The month of Ramadan in which the Qur'an was sent down to be a guidance to the people and as clear signs of the Guidance and the Discrimination. Let those of you who are present at the month last it.' (2: 185)
