One night I had in the desert of Mekkah become so weak from want of sleep that I was unable to walk and, laying myself down, told the camel driver to let me alone.

How far can the foot of a wretched pedestrian go
When a dromedary gets distressed by its load?
Whilst the body of a fat man becomes lean
A weak man will be dead of exhaustion.

He replied: -O brother, the sanctuary is in front of us and brigands in the rear. If thou goest thou wilt prosper. If thou sleepest thou wilt die.-

It is pleasant to sleep under an acacia on the desert road
But alas! thou must bid farewell to life on the night of departure.
