The Messenger of Allah (Sallallahu ta’ala alayhi wa sallam) said:
“Allah the Exalted said: Every deed of the son of Adam is for him except fasting, for it is done for My sake and I will reward it.” The Prophet added, “By Allah in whose Hand is the soul of Mohammed, the (bad) breath of a fasting person is sweeter to Allah than the fragrance of musk.”
