Abu Hurairah (ra) narrated that Allah’s Messenger said “When the month of Ramahdan starts, the gates of heaven are opened and the gates of Hell are closed and the devils are chained.” (Sahih al-Bukhari). Abu Hurairah (ra) also narrated that Allah’s Apostle said “Allah said, ‘All the deeds of Adam’s sons (people) are for them, except fasting which is for Me, and I will give the reward for it.’ Fasting is a shield or protection from the fire and from committing sins. If one of you is fasting, he should avoid marital relations with his wife and quarrelling, and if somebody should fight or quarrel with him, he should say, ‘I am fasting.’ By Him in Whose Hands my soul is, The unpleasant smell coming from the mouth of a fasting person is better in the sight of Allah than the smell of musk. There are two pleasures for the fasting person, one at the time of breaking his fast, and the other at the time when he will meet his Lord; then he will be pleased because of his fasting.” (Sahih al-Bukhari).
