Musannaf Ibn Abi Shaybah 14085 — A man who vows to walk to the House

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) saw a man walking with great difficulty, supported between two men (the narrator Yazid said: he was walking supported by his two sons). He (peace and blessings be upon him) asked: "What is this?" The Companions said: This man has vowed that he will walk to the House of Allah. He (peace and blessings be upon him) said: "Indeed, Allah Almighty is free of need of this man putting himself through such hardship. Go and tell him to ride."
