Sayyiduna Anas bin Malik (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) called the Ansar in order to allot them land in Bahrain. They said: We will not take it until you grant our brothers from the Muhajirun the like of it as an estate. The Messenger of Allah (peace and blessings be upon him) said: "After me you will see others being given preference over you, so be patient until you meet me."
