If a person does not know the number of days he fasted, what should he do?

Question:
The questioner, Shaimba, says: I have days from the fasting of Ramadan that I broke in previous years for an excuse and did not make up, and now I cannot count them exactly. What is obligatory for me now, and is there an expiation?

Answer:
You erred in delaying to the point where you forgot the number of days. It is obligatory to hasten to make them up, because it is a debt in your conscience and it is not permissible to delay it without an excuse. As for the fact that you forgot the number, you should estimate the number of days, exerting yourself in estimating it, and act on the most cautious option. So if it is most likely in your opinion that it is ten days, for example, and you hesitate between it being ten days or nine days, make it ten, in order to be certain that you have fulfilled the obligation. You must hasten to make them up, and along with making them up, you must feed one poor person for each day, as a ransom for the delay. Yes.
