—and other similar reports—are treated as marfūʿ (traced back to the Prophet), for they represent his ﷺ tacit approval.

Important notice:
If a menstruating or postpartum woman becomes pure before sunset, she must perform both the Ẓuhr and ʿAṣr prayers of that day; and if she attains purity before dawn, she must perform both Maghrib and ʿIshāʾ of that night, because in cases of excuse the time allotted for the later prayer is also considered time for the earlier one.

Shaykh al-Islām Ibn Taymiyyah said in al-Fatāwā 22/434: “For this reason the majority of scholars—Mālik, al-Shāfiʿī, and Aḥmad—hold that when a menstruating woman becomes pure at the end of the day she performs both Ẓuhr and ʿAṣr, and when she becomes pure at the end of the night she performs both Maghrib and ʿIshāʾ. This was reported from ʿAbd al-Raḥmān ibn ʿAwf, Abū Hurayrah, and Ibn ʿAbbās, because the time is shared between the two prayers when an excuse exists. Thus, if she becomes pure at the end of the day, the time for Ẓuhr is still in effect, so she prays it before ʿAṣr; and if she becomes pure at the end of the night, the time for Maghrib is still in effect in the case of an excuse, so she prays it before ʿIshāʾ.” End quote.
