وَعُبَيْدَةُ، عَنْ إِبْرَاهِيمَ، فِي الْمَرْأَةِ تُفَرِّطُ فِي الصَّلَاةِ حَتَّى يُدْرِكَهَا الْحَيْضُ، قَالُوا: "تُعِيدُ تِلْكَ الصَّلَاةَ" ..
It is narrated from Imam Hasan, Imam 'Amir Sha'bi, and Imam Ibrahim (may Allah have mercy on them) regarding a woman who is negligent in her prayers and then menstruation occurs to her, they said: She will perform (make up) that prayer (i.e., after purification, she will have to perform those missed prayers).
