of the opening takbir, then according to the school’s position she has caught Maghrib; but according to the view that a complete rak‘ah is required, she has not caught it. A further question follows from this: if she becomes pure from menstruation, must she make up this prayer or not?
The answer is: according to the school’s position, she must make it up; according to the second view, she does not have to make it up.
There is a third view concerning this particular issue: she is not required to make it up unless she delayed the prayer until its time had become too short to perform it, and then menstruated. In that case, she must make it up. They explain this by saying that a woman has the right to delay the prayer until the time becomes restricted to the extent needed to perform it; thus, if she delays it, she is not sinful. If the impediment then comes upon her at a time when she is not sinful, she is not deemed negligent. Moreover, it appears from the practice of the women among the Companions that, if they menstruated during the prayer time, they would not make up that prayer—though it is possible that, when anticipating menstruation, they would perform the prayer at the beginning of its time for fear that menstruation might occur. And Allah knows best.
2—If a woman becomes pure from menstruation before sunset with only enough time remaining for the opening takbir, then according to the school’s position, she must perform Asr, as well as Zuhr, since Zuhr is combined with it.
According to the second view, she is required to perform neither Asr nor Zuhr: Zuhr is only required consequentially, while Asr is not required because she did not catch enough of the time for a complete rak‘ah.
Issue: If a woman becomes pure from menstruation before sunset with enough time remaining for one rak‘ah, then she must perform Asr according to both views.
