We pray not, because we must drink the water of ablution.
We give no alms, because we ask them.
We fast not the Ramazan month, because we starve throughout the year.
And we do no pilgrimage, because the world is the house of Allah.
-- Sir Richard Francis Burton, Narrative of a Pilgrimage to Meccah and Medinah (London: William Mullan and sons, 1879), p. 370.
