vowed to fast for ten days beginning from the moment when I receive news that I had passed my exams and received my Bachelor's degree.
After the exams, I got the results and praise be to Allah I succeeded. Accordingly, I fasted on that day and the day after, but I was very exhausted on the second day. This was because on one hand it was summer, (Part No. 23; Page No. 372) and also because I was affected by the failure of some of my friends. I was not even able to break my fast due to extreme fatigue, and therefore I refrained from fasting during that period. I did not know what to do, especially after I vowed to fast these days consecutively, i.e. by an oath which I broke. So please provide me with the answer about this, may Allah reward you.
You have to fulfill the vow you took, and fast these consecutive days. You must also offer a Kaffarah (expiation) of oath for failing to fast these days at the time you specified by clothing ten Masakeen (needy persons), or feeding them half a Sa` (1 Sa`=3 kg. Approx.) each, which is approximately equal to a kilo and a half, or freeing a believing bondsman.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
