Vowing to fast on Mondays and Thursdays until he dies

Q: Three years ago, I said that I would observe Sawm (fasting) on Mondays and Thursdays for my whole life. Nowadays, I am not able to observe Sawm due to the lack of Iman (faith). Please advise whether this is a vow or a voluntary act. What is the ruling on it, given that I said I will observe Sawm without a condition? Should I observe Sawm or not? Do I have to pay Kaffarah (expiation)? May Allah reward you.

A: Saying "I will observe Sawm" is not a vow; it is just a promise. Thus, you do not have to abide by observing Sawm on Mondays and Thursdays. And Allah knows best.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
