I never complained at the vicissitudes of fortune, nor murmured at the ordinances of Heaven, excepting once, when my feet were bare, and I had not the means of procuring myself shoes. I entered the great mosque at Cufah with a heavy heart when I beheld a man who had no feet. I offered up praise and thanksgiving to God for his bounty, and bore with patience the want of shoes.
