The great Muslim poet Jalal al-Din Rumi sang about Ramadan in the 13th century AD (translation by A.J. Arberry):

"The month of fasting has come, the emperor's banner has arrived;
withhold your hand from food, the spirit's table has arrived.

The soul has escaped from separation and bound nature's hands;
the heart of error is defeated, the army of faith has arrived.

Fortitude is as a sweet cloud, wisdom rains from it,
because it was in such a month of fortitude that the Koran arrived.

...Wash your hands and your mouth, neither eat nor speak;
seek that speech and that morsel which has come to the silent ones."
