How Many Fasts Should I Make Up If I’m Not Sure?

Shafi'i Fiqh

Answered by Ustadha Shazia Ahmad


Unfortunately, I used to masturbate, not knowing that this would break my fast and require a bath before praying. I have now repented. However, I do not know how many fasts I broke. I can only remember doing the act while fasting twice, but I am pretty sure I did this more than twice. How many fasts do I need to make up?


Thank you for your question. May Allah reward you for leaving your habit in the past, repenting, and transforming yourself. I pray that others derive strength from your example.


I advise you to take some time to calculate to the best of your ability how many fasts you have missed; overestimate a little. Record or make a document with this information, then make a schedule to make up these fasts gradually.

Take advantage of fasting on the blessed sunna days such as; the tenth Muharram, the day of `Ashura with the day before it or after it, the six days of Shawwal, the first nine days of Dhu’l Hijjah, the white days, Mondays and Thursdays, the 15th of Sha`ban, and others.
