It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: By Him in Whose hand is the soul of Muhammad (peace and blessings be upon him), the breath of the fasting person is more pleasant to Allah than the fragrance of musk. Allah Almighty says: My servant leaves his food, drink, and desires for My sake, so fasting is for Me and I Myself will give its reward, and apart from fasting, the reward of every good deed is multiplied from ten to seven hundred times.
