Musannaf Ibn Abi Shaybah

Hazrat Abdullah bin Zaid (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: If migration were not an important matter, I would have been one of the Ansar myself. If people were to walk in one valley or mountain pass, I would walk in the valley or mountain pass of the Ansar. The Ansar are to me like the inner part of a garment, and the rest of the people are like the outer part of a garment to me. And indeed, soon you will see that others will be given preference over you. So be patient until you meet me at the Pond of Kawthar.
