Abu Huraira (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he said: By Him in Whose hand is the life of Muhammad (peace and blessings be upon him), the son of Mary (peace be upon him) will surely proclaim Talbiyah in the valley of "Rawha". He will either be performing Hajj, or Umrah, or both Hajj and Umrah together.
