If menstrual blood or post-natal bleeding comes out a moment after the sun has set, does the fasting woman break her fast?

The questioner : Now, if menstrual blood or post-natal bleeding comes out a moment after the sun has set. Please.

The Shaykh : Yes, yes. After the sun has set. A brief answer. A brief one. Unlike the women, who say that if the menstruation ends before she prays Maghrib, she must make up that day. This is not correct. It is perhaps based on the view that the movement of the fluid is like its exit. The view that the movement is like the exit is a weak view, because the rulings are contingent upon the exit. For this reason, the Messenger (peace and blessings be upon him) said: Rather, if she sees the water. So the Prophet (peace and blessings be upon him) made the ruling contingent upon the sight, and the sight does not occur except after the exit. Therefore, the view that the movement of semen or the movement of menstrual blood is like its exit is a weak view, and the evidence is against it.
