I complained I had no shoes

Help all ... I am looking for the origin of this:
"I complained I had no shoes, untill I met a man who had no feet" thanks all

". . . once, when my feet were bare, and I had not the means of obtaining shoes. I came to the chief of Kufah in a state of much dejection, and saw there a man who had no feet. I returned thanks to God and acknowledged his mercies, and endured my want of shoes with patience . . ."
