Musannaf Ibn Abi Shaybah 13018 — One who dies owing a vow

Sayyiduna Sinan bin Abdullah al-Juhani (may Allah be pleased with him) narrates from his paternal aunt that she came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him)! My mother has died, and she owed a vow to walk to the Ka'bah." He (peace and blessings be upon him) asked: "Are you able to walk on her behalf?" I said: "Yes." He (peace and blessings be upon him) said: "Then walk on behalf of your mother." I said: "Will that suffice for her?" He (peace and blessings be upon him) said: "Yes. What do you think: if she owed a debt and you paid it, would that debt be accepted from you?" I said: "Yes." He (peace and blessings be upon him) said: "Allah Almighty is more entitled to that."
