It is narrated from Hazrat Anas that the Noble Prophet (peace and blessings be upon him) saw a man who was walking with great difficulty, supported by two men. Yazid, the narrator, says that he was walking with the support of his two sons. The Prophet (peace and blessings be upon him) asked: What is this? The companions replied that this man had made a vow to go to the House of Allah on foot. The Prophet (peace and blessings be upon him) said: Surely Allah is free from needing this person to put himself in such hardship. Go and tell him to ride (an animal) and go.
