The Adventures of Haroun-al-Raschid, Caliph of Bagdad

They all bowed themselves low before the throne and then the Caliph bade them rise, and ask the blind man his name.

"Baba-Abdalla, your Highness," said he.

"Baba-Abdalla," returned the Caliph, "your way of asking alms yesterday seemed to me so strange, that I almost commanded you then and there to cease from causing such a public scandal. But I have sent for you to inquire what was your motive in making such a curious vow. When I know the reason I shall be able to judge whether you can be permitted to continue to practise it, for I cannot help thinking that it sets a very bad example to others. Tell me therefore the whole truth, and conceal nothing."

These words troubled the heart of Baba-Abdalla, who prostrated himself at the feet of the Caliph. Then rising, he answered: "Commander of the Faithful, I crave your pardon humbly, for my persistence in beseeching your Highness to do an action which appears on the face of it to be without any meaning. No doubt, in the eyes of men, it has none; but I look on it as a slight expiation for a fearful sin of which I have been guilty, and if your Highness will deign to listen to my tale, you will see that no punishment could atone for the crime."
