Muslim narrated in Al-Sahih on the authority of Abu Saeed Al-Khudri, who said that the Messenger of God, may God’s prayers and peace be upon him, said: “There is no servant who fasts a day for the sake of God except that God removes his face on that day from Hellfire for seventy years.

So he mentioned the fasting of slaves, not the fasting of free people. ” The slaves are few in status and by belief they are all, and fasting is a divine analogy and that is why He denied it from the slave.

By God Almighty’s saying, “Fasting is for me, and the slaves have nothing from fasting except hunger. ”

So the exaltation in fasting is for God and hunger is for the servant .
