[Machine] When this verse was revealed in Surah Al-Baqarah, some people said, "The number of women mentioned in the verse is less than the actual number of women, as it does not include young or elderly women who no longer experience menstruation, or pregnant women." So Allah revealed the following verse in Surah At-Talaq: "And those who no longer expect menstruation among your women - if you doubt, then their period is three months, and [also for] those who have not menstruated. And for those who are pregnant, their term is until they give birth." Ash-Shafi'i, may Allah have mercy on him, said regarding the statement "if you doubt" in Surah At-Talaq, "You do not know what would be the limit for other than the mature [women]."  

لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ الَّتِي فِي سُورَةِ الْبَقَرَةِ فِي عَدَدٍ مِنْ عِدَدِ النِّسَاءِ قَالُوا قَدْ بَقِيَ عَدَدٌ مِنْ عِدَدِ النِّسَاءِ لَمْ يَذْكُرْنَ الصِّغَارَ وَالْكِبَارَ اللَّائِي انْقَطَعَ عَنْهُنَّ الْحَيْضُ وَذَوَاتُ الْأَحْمَالِ فَأَنْزَلَ اللهُ ﷻ الْآيَةَ الَّتِي فِي النِّسَاءِ {وَاللَّائِي يَئِسْنَ مِنَ الْمَحِيضِ مِنْ نِسَائِكُمْ إِنِ ارْتَبْتُمْ فَعِدَّتُهُنَّ ثَلَاثَةُ أَشْهُرٍ وَاللَّائِي لَمْ يَحِضْنَ وَأُولَاتُ الْأَحْمَالِ أَجَلُهُنَّ أَنْ يَضَعْنَ حَمْلَهَنَّ} [الطلاق 4] قَالَ الشَّافِعِيُّ رَحِمَهُ اللهُ وَقَوْلُهُ {إِنِ ارْتَبْتُمْ} [الطلاق 4] فَلَمْ تَدْرُوا مَا تَعْتَدُّ غَيْرُ ذَوَاتِ الْأَقْرَاءِ
