It also follows that if a woman’s menstruation ends with enough time remaining before sunset for one rak'ah, she must offer the ‘Asr prayer. If it ends with enough time remaining before dawn for one rak'ah, she must offer the ‘Ishā’ prayer. If less than the time needed for one rak'ah remains, neither prayer is obligatory upon her.

As for the Zuhr and Maghrib prayers, must she also offer them in these circumstances? There is a well-known disagreement on this point. One view holds that she need not do so; this is the position of Abū Hanīfah. Another holds that she must; this is the position of Mālik, al-Shāfi‘ī, and Ahmad. Imam Ahmad also related this view from Ibn ‘Abbās and ‘Abd al-Rahmān ibn ‘Awf.

Those who hold the latter view then differed over how much time must remain for the earlier prayer to become obligatory. They held two opinions:

The first is that it becomes obligatory when enough time remains to make the second prayer obligatory. Whether this means the time needed for one rak'ah or for saying “Allah is greatest” once is itself a matter of two opinions.

The second is that the earlier prayer becomes obligatory only if she has enough time remaining to perform it. This is the more correct view.

A similar disagreement concerns a woman who is free of menstruation when the prayer time begins, but whose menstruation then starts: must she make up that prayer or not? There are two opinions. The first is that she need not make it up, as Mālik and Abū Hanīfah maintain. The second is that she must, as al-Shāfi‘ī and Ahmad maintain.
