Yahya bin Sa'id says that he heard Sayyiduna Anas (may Allah be pleased with him) say that the Messenger of Allah (peace and blessings be upon him) called the Ansar in order to write a deed for them for land in Bahrain. They said: By Allah! We will not take it until you do the same for our brothers from Quraysh. He (peace and blessings be upon him) kept saying that to them for as long as Allah willed, and each time they said the same. He (peace and blessings be upon him) said: "Indeed, after me you will see others being given preference over you, so be patient until you meet me."
