Ramadan Q&A (4/14)

Fasting is a salient feature of Islam. To openly eat and drink during the month of Ramadhaan is tantamount to showing disregard to the salient feature of Islam and a major sin. If the one who does not fast and openly eats and drinks regards it as a sin but does so due to weakness of Imaan he will be guilty of a major sin but will not come out of the fold of Islam. If he believes that there is no sin in what he is doing then such a person has regarded this salient feature of Islam as insignificant. Hence this will render him out of the fold of Islam.
