Ibrahim Mouseli relates the following story: "Rashid one day summoned all his musicians. I and Meskin of Medina were among the performers. Rashid had partaken freely of wine, and wished to hear performed an air which had suddenly occurred to his mind. The officer stationed before the curtain which concealed the Caliph told Ibn Jami to sing this piece. The latter obeyed, but did not succeed in pleasing the Caliph. Each of the singers present attempted it, but were no more successful than Ibn Jami. Then the officer, addressing Meskin, said: 'The Commander of the Faithful orders you to sing this air if you can do it properly.' "Meskin commenced at once to sing, to the great surprise of the audience, who could not understand how a musician like him had the courage to attempt, before us, an air which none of us had been able to render to the satisfaction of the Caliph. As soon as he had finished I heard Rashid raise his voice and ask to hear it a second time. Meskin recommenced with a skill and spirit which won him everybody's applause. The Caliph congratulated and praised him to the skies; then he had the curtain behind which he had been sitting drawn aside. "'Prince of the believers,' then said Meskin to him, 'a strange story attaches to this piece'; and at the invitation of the Caliph he narrated it in these words: 'I was formerly a slave of a member of the family of Zobeir, and carried on the trade of a tailor. My master claimed from me a tax of two dirhems daily, after paying which I was free to do what I liked. I was passionately fond of singing. One day a descendant of Ali, for whom I had just completed a tunic, paid me two dirhems for it, kept me to eat with him, and made me drink generously. As I left him I met a negress carrying her pitcher on her shoulder, and singing the song you have just heard. I was so delighted at it that, forgetting everything else, I said to her: "By the Prophet, I adjure thee to teach me that air." "By the Prophet," she answered, "I will not teach it unless you pay me two dirhems." "'Then, Prince of believers, I took out the two dirhems, with which I had intended to pay my daily tax, and gave them to the negress. She, setting her pitcher down, sat on the ground and, keeping time with her fingers on the pitcher, sang the piece, and repeated it till it was well impressed on my memory.
