Maliks Muwatta Book 022, Hadith Number 002.

Section : Fulfilling Vows to Walk.

Yahya related to me from Malik from Abdullah ibn Abi Bakr that his paternal aunt related that her grandmother made a vow to walk to the Quba mosque. She died, and did not fulfil it, so Abdullah ibn Abbas asked her daughter to walk for her.

Yahya said that he had heard Malik say, "No one walks for anyone else."
