The great Indian poet Iqbal said about fasting:

Fasting makes an assault upon hunger and thirst.
And breaches the citadel of sensuality...
Almsgiving causes love of riches to pass away
And makes equality familiar;
It fortifies the heart with righteousness,
It increases wealth and diminishes fondness for
wealth.
All this is a means of strengthening thee:
Thou art impregnable, if thy Islam be strong.
Draw might from the litany "O Almighty One!"
That thou mayst ride the camel of thy body.
