Numerous Oaths of Unknown Number and the Overlapping of Expiations

Question:
I have made many oaths regarding various matters, and I am not certain of the number of these oaths. What is the ruling? May Allah reward you.

Answer:
The ruling is that if you know the number, you must expiate for them. If you do not know the number, you must estimate them and exercise caution. If you are unable to estimate, then you owe nothing, because you do not know the number of these oaths, nor do you know their types or what is required in them, until you know them precisely or by estimation. If you are unable to do both—neither precise knowledge nor estimation—then you must wait until the forgetfulness is lifted, or you wait, meaning you wait, perhaps you will remember. Yes, yes.
If one swears several oaths regarding one single matter, several oaths whose consequence is one, oaths by Allah the Exalted, all oaths by Allah regarding one single matter, then he expiates with one expiation, because they overlap under two conditions. The first condition is that they are all of the same type, for example, oaths by Allah. The second condition is that the consequence is one, meaning one oath of zihar, one oath of divorce, or one oath by Allah the Exalted. These have their own rulings. Yes.
