Does a Person who Promised Not to do a Sin without Mentioning Allah’s Name, Have to Do Expiation (Kaffara)?

Hanafi Fiqh

Answered by Shaykh Yusuf Weltch

Question

Is it considered an oath, and is Kaffara (expiation) required if someone makes a dua promising not to commit a sin but does not mention Allah’s name?

Answer

In the Name of Allah, the Most Merciful and Compassionate

A promise is different than a vow or an oath. If one does not swear by the Name of Allah Most High, this does not obligate fulfillment such that expiation is due for non-fulfillment. [Maydani, al-Lubab fi Sharh al-Kitab]

A promise, however, should not be taken lightly, and one should try their best to fulfill their promises. This is even more important when the promise is made to Allah Most High.

Constant non-fulfillment of promises, breaking of promises intentionally, and neglecting the fulfillment of promises is sinful and a sign of hypocrisy. [Nahlawi, al-Durar al-Mubaha]

The Messenger of Allah (may Allah bless him and give him peace) said, “The signs of the hypocrite are three: when they speak, they lie; when they promise, they break their promise; and when they are entrusted, they betray that trust.” [Bukhari; Muslim]
