What is the difference between menstruation and post-natal bleeding in the waiting period?

Question : It is a small amount. What is the evidence for that?

Answer : Yes, the scholars say the difference is that menstruation is a customary matter, and Allah the Exalted has set four months for this husband. He, Glorified and Exalted is He, knows that most women menstruate once every month. As for post-natal bleeding, it is a rare matter, and it is a state that requires the one who pronounces the divorce not to be inclined toward the wife during the bleeding. Yes, they say that the verse is absolute, but based on the fact that this is a rare excuse, which is post-natal bleeding, it is not counted. And the issue is not free from scholarly disagreement.
