question #3 Sahih Muslim 1151b, Book 13, Hadith 210 : What is the significance of the breath of a fasting person being described as sweeter than musk to Allah?

Allah, the Majestic and the Exalted, said: Every act of the son of Adam is for him except fasting. It is done for My sake, and I will give a reward for it. By Allah in Whose Hand is the life of Muhammad, the breath of the observer of fast is sweeter to Allah than the fragrance of musk.
