Sayyiduna al-Adda' bin Khalid bin Hawdhah (may Allah be pleased with him) said that he brought out a document before us and said that the Messenger of Allah (peace and blessings be upon him) had written it for me concerning this water at which I (now) am; this land was granted to me by him (peace and blessings be upon him) as an allotment (qati'ah).
