Is an oath conditional upon the wife performing an action she is capable of, or another person performing an action, considered an Iilaa'?
General Chapter
Al-Mughni
Book of the Oath of Abstention (Ila')
Primary text
If the condition is a permissible act by the wife or another party that involves no hardship, such as entering a house, wearing a specific garment, observing a voluntary fast, or being clothed by the husband, it is not an Iilaa' because it is easily achievable without harm to her, placing it in the same category as the previous case.

If the condition is an unlawful act, such as drinking alcohol, committing adultery, causing a miscarriage, or abandoning an obligatory prayer, the oath is considered an Iilaa' because the condition is legally impossible, similar to a physically impossible condition. Furthermore, if the condition requires the wife to relinquish her property rights, such as forfeiting her Mahr, guaranteeing a debt, or gifting her house, or requires her father to sell his house, it is an Iilaa' because seizing another's property without consent is unlawful, analogous to drinking wine. However, if the condition is for the husband to give her money or treat her kindly, it is not an Iilaa' because the husband's action is neither prohibited nor impossible, resembling the condition of fasting for a day.
