Swearing that someone vows to Allah to do something

Q 1: I took an oath saying for three times, "By Allah, this is a vow incumbent on me that you should do that thing;" and I named that thing. However, he did not do it. What is the Kaffarah (expiation) for that oath?

A: You must offer one Kaffarah only for the unfulfilled oath and vow, as they have been taken regarding one thing. (Part No. 23; Page No. 108) The Kaffarah is to feed ten Miskins (needy persons), or provide them with clothing, or emancipate a believing slave. If you cannot afford any of them, you must observe Sawm (Fast) for three days.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
