Muwatta Malik 1030

Yahya related to me from Malik from Ayyub ibn Musa from Mansur ibn Abd ar-Rahman al-Hajabi from his mother that A'isha, umm al- muminin, may Allah be pleased with her, was asked about a man who devoted his property to the door of Kaba. She said, "Let him do kaffara for it with the kaffara of the oath." Malik said, that someone who devoted all his property in the way of Allah, and then broke his oath, should put a third of his property in the way of Allah, as that was what the Messenger of Allah, (ﷺ), did in the case of Abu Lubaba.
