Musannaf Ibn Abi Shaybah 12817 — A man and a woman who swear to walk

Amr bin Sa'id al-Bajali said: Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him) was on the pulpit and I was sitting below (in front of) the pulpit. A man came and said: O Commander of the Believers! I had vowed that I would perform Hajj on foot. When I had travelled such-and-such a distance on foot, I feared that I would miss the Hajj, so I rode. He said: There is no wrong upon you. Return next year, walk what you rode and ride what you walked.
