Sayyiduna Razin bin Anas al-Sulami (may Allah be pleased with him) narrated: When Islam appeared, we had a well at al-Dunaynah, and we feared that the people around us would seize it from us. He said: So I came to the Prophet (peace and blessings be upon him) and mentioned that to him (peace and blessings be upon him). He (peace and blessings be upon him) had a document written for me: "From Muhammad, the Messenger of Allah (peace and blessings be upon him). To proceed: their well belongs to them, if he is truthful." He said: Then whenever we took a dispute over it to any of the judges of Madinah, he ruled in our favour. He said: The document of the Prophet (peace and blessings be upon him) was like this (in detail), and he held that the document of the Prophet (peace and blessings be upon him) was like this.
