A man and his slave went to Mashhad and they both went to visit the Shrine. Then the man started to pray at the position of the Imam’s head, and the slave started to pray at the position of the Imam’s feet. Then when they finished praying, they both prostrated - long prostrations. Then the man rose up his head from the position of prostration before his slave did and called out to his slave. The slave rose up his head from the position of prostration and said, “Yes, my master!”Then the man asked him, “Do you want me to set you free?” He said, “Yes.” The man said, “You are set free for the sake of God the Highest. I also set my female slave in Balkh free for the sake of God. I marry her off to you for such and such an amount of nuptial gift for which I take responsibility on your behalf. I also endow such and such property for both of you, your children and your grand-children from your progeny. Be this Imam Ar-Ridha’ (a.s.) a witness to this.” Then the slave man cried and attested by God the Highest and the Imam (a.s.), that this was exactly what he had asked for in his prostration. And he recognized that prayers were quickly fulfilled by God the Highest.”
