He reported God’s messenger as saying, "Every [good] deed a son of Adam does will be multiplied, a good deed receiving a tenfold to seven hundredfold reward. God has said, ‘With the exception of fasting, for it is done for my sake and I give a reward for it. One abandons his passion and his food for my sake.* The one who fasts has two occasions of joy, one when he breaks his fast and one when he meets his Lord. The bad breath of one who fasts is sweeter to God than the fragrance of musk. Fasting is a protection, [i.e. from acts of disobedience in this world and from hell in the next. Pt. vi.] and when the day of the fast of any of you comes he must not use vile language or raise his voice, and if anyone reviles him or tries to fight with him he should tell him he is fasting.” *This is not from the Qur’an, but is a hadith qudsi, a tradition which gives words spoken by God. (Bukhari and Muslim.)
