It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: If people were walking in one valley and the Ansar in another valley, I would walk with the Ansar in their valley. If there had been no migration, I would have been one of the Ansar.
