Narrated by Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) combined Hajj and Umrah in one Ihram due to the fear that he might be prevented from reaching the House of Allah. Then he said: And it was his (peace and blessings be upon him) thought that if Hajj could not be performed, then at least Umrah would be completed.
