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.
