It is narrated from Ayyub (may Allah have mercy on him) that he said: "We saw with Thumamah bin Abdullah bin Anas (may Allah have mercy on him) a document (a written decree) which Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) had written for Sayyiduna Anas bin Malik (may Allah be pleased with him) when he (may Allah be pleased with him) sent him as the official over the zakah (collection) of Bahrain. It bore the blessed seal of the Prophet (peace and blessings be upon him), and in it was the same statement (or ruling) as has passed above."
