The ruling on the waiting period in the case of a second divorce during the first waiting period

Question:
Honorable Shaykh, if a man divorces his wife with the second divorce after two months have passed, does the waiting period from the second divorce become invalid, or what is the ruling?

Answer:
He does not see the first one, so the waiting period is from the first divorce, if he did not take her back, then it is from the first one. But if he took her back and then divorced her during the waiting period, then the waiting period remains from the second divorce because it occurred after he took her back.
