What is the ruling of the Shari'ah regarding a mother's vow that her daughter donate half of her salary, and what must be done concerning the current obligations?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
If your wife's mother vowed to donate half of what her daughter collects, this vow is invalid; because it is a vow concerning something she does not own. The Prophet, peace and blessings be upon him, said: "There is no fulfillment for a vow made in disobedience [to Allah], nor for something that a servant does not own." The mother is not required to offer expiation according to the majority of scholars. Some scholars said that it is forbidden to make a vow involving another person's property.
