T-S AS 159.172
One side: A brief letter to Abu l-Rabīʿ Sulaymān consisting of greetings and blessings. (A man by the same name is known from India Book 4, as one of Yehuda ha-Levi's companions in his trip to Alexandria, but the name is common, and there is no sign that this is the addressee here.) The other side: Seems to be in the same hand, also consisting entirely of deferential blessings (kissing hands and feet, etc.)
