The Philosophy of Fasting in Ramadan:

Fasting kills the desire of the self and the appetite of greed, and from it comes purity of the heart, purification of the limbs, cultivation of the inner and the outer being, thankfulness for blessings, charity to the poor, increase of humble supplication, humility, weeping and most of the ways of seeking refuge in Allah; and it is the cause for the breaking of worldly desires, the reducing of evil things, and the redoubling of good deeds. It contains benefits which cannot be counted. It is enough that we mention some of them to the person who understands and is given success in making use of fasting, if Allah wills.”
