Mukhtasar Muslim (Abridged) 1004 — Vowing to walk to the Kaaba

`Sayyiduna Uqbah bin Amir (may Allah be pleased with him) says that` my sister made a vow to walk barefoot to the House of Allah, so she asked me to inquire from the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) said that she may walk and also ride.
