It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) saw an elderly companion walking on foot between his two sons, so he asked,“What has happened to this elder?”(that he is walking with your support). His sons replied,“O Messenger of Allah (peace and blessings be upon him)! He has made a vow to go (for Hajj) on foot.”The Prophet (peace and blessings be upon him) said,“O elder! Ride, for Allah is free of need from you and your vow.”(That is, Allah has no need of it. In Sahih Bukhari it is stated:“Allah is independent (free of need) of this person putting himself in hardship.”)
