Yahya bin Sa'id (may Allah have mercy on him) said: Sayyiduna Anas bin Malik (may Allah be pleased with him) came to us in Madinah. He narrated to us that the Messenger of Allah (peace and blessings be upon him) granted the land of Bahrain to the Ansar as a fief, and he (peace and blessings be upon him) intended to write it down for them. They said: "No, not until the Quraysh are also given the like of it." The Prophet (peace and blessings be upon him) said: "After me you will see others preferred over you, so be patient until you meet me."
