What did Allah, the Majestic and Exalted, say about the act of fasting done for His sake according to the words of the Prophet Muhammad (peace be upon him)?
 Abu Huraira reported Allah's Messenger (may peace be upon him) as saying:                      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.
