It is narrated from Hazrat Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) saw a man walking while taking support on the shoulders of his two sons. He asked, "What is the matter with him?" They informed him that he had vowed to perform Hajj on foot. The Prophet (peace and blessings be upon him) said, "Allah is free from need of this man putting himself in hardship." Then the Prophet (peace and blessings be upon him) ordered him to ride, so he rode.
