[Machine] The woman should recite when her menstruation approaches, and should recite when her purity approaches. Abu 'Ubaid said: "The time of recitation is when the act is present." Al-A'sha praised a man for a battle in which he inherited wealth, and in the mention of him, there is an elevation for what was lost in it from the recitation of your women. So, the recitation here refers to purification, because women are not approached except in a state of purity.  

قَدْ أَقْرَأَتِ الْمَرْأَةُ إِذَا دَنَا حَيْضُهَا وَأَقْرَأَتْ إِذَا دَنَا طُهْرُهَا قَالَ قَالَ أَبُو عُبَيْدٍ فَاصِلُ الْأَقْرَاءِ إِنَّمَا هِيَ وَقْتُ الشَّيْءِ إِذَا حَضَرَ قَالَ الْأَعْشَى يَمْدَحُ رَجُلًا بِغَزْوَةٍ غَزَاهَا [البحر الطويل] مُوَرِّثُهُ مَالًا وَفِي الذِّكْرِ رِفْعَةٌ لِمَا ضَاعَ فِيهَا مِنْ قُرُوءِ نِسَائِكَا فَالْقُرُوءُ هَاهُنَا الْأَطْهَارُ لِأَنَّ النِّسَاءَ لَا يُوطَأْنَ إِلَّا فِيهَا
