When should a missed prayer be made up if menstruation began after its due time, and there was sufficient time to perform it, but it was not performed: Should it be made up upon purification (even if it's during the time of Isha' prayer), or when the time for the next similar prayer enters (the following Dhuhr)? And must the Maghrib and Isha' prayers be performed if purity is attained within their respective times?

If menstruation begins after the prayer time has entered, with enough time to perform one unit (rak'ah) of prayer, then that prayer must be made up after purity, based on the Prophet's (peace be upon him) saying: "Whoever catches one rak'ah of the prayer has caught the entire prayer." The making up (qada') should be done immediately upon purity.

If a woman becomes pure before the prayer time expires, that prayer becomes obligatory upon her, as well as the prayer that is combined with it according to the majority of scholars. Thus, whoever becomes pure before sunset must pray Dhuhr and Asr. Whoever becomes pure before Fajr must pray Maghrib and Isha. And whoever becomes pure before sunrise must pray Fajr.
