Sayyiduna Anas (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) saw a man being supported by two men. He (peace and blessings be upon him) said: "What is the matter with him?" They said that he would walk to the House of Allah. He (peace and blessings be upon him) said: "Allah has no need of this man tormenting himself; tell him to ride."
