Once Messenger of Allah ﷺ went out to the Musalla (to offer the prayer) of ʿId-al-Adha or Al-Fitr prayer. Then he passed by the women and said, "O women! Give alms, as I have seen that the majority of the dwellers of Hell-fire were you (women)." They asked, "Why is it so, O Messenger of Allah ﷺ ?" He replied, "You curse frequently and are ungrateful to your husbands. I have not seen anyone more deficient in intelligence and religion than you. A cautious sensible man could be led astray by some of you." The women asked, "O Messenger of Allah ﷺ! What is deficient in our intelligence and religion?" He said, "Is not the evidence of two women equal to the witness of one man?" They replied in the affirmative. He said, "This is the deficiency in her intelligence. Isn't it true that a woman can neither pray nor fast during her menses?" The women replied in the affirmative. He said, "This is the deficiency in her religion." (Using translation from Bukhārī 304)   

خَرَجَ رَسُولُ اللهِ ﷺ فِي أَضْحَى أَوْ فِطْرٍ إِلَى الْمُصَلَّى ثُمَّ انْصَرَفَ فَقَامَ فَوَعَظَ النَّاسَ وَأَمَرَ النَّاسَ بِالصَّدَقَةِ فَقَالَ أَيُّهَا النَّاسُ تَصَدَّقُوا ثُمَّ انْصَرَفَ فَمَرَّ عَلَى النِّسَاءِ فَقَالَ يَا مَعْشَرَ النِّسَاءِ تَصَدَّقْنَ؛ فَإِنِّي أُرِيتُكُنَّ أَكْثَرَ أَهْلِ النَّارِ فَقُلْنَ وَبِمَ ذَلِكَ يَا رَسُولَ اللهِ قَالَ تُكْثِرْنَ اللَّعْنَ وَتَكْفُرْنَ الْعَشِيرَ وَمَا رَأَيْتُ مِنْ نَاقِصَاتِ عَقْلٍ وَدِينٍ أَذْهَبَ بِلُبِّ الرَّجُلِ الْحَازِمِ مِنْ إِحْدَاكُنَّ يَا مَعْشَرَ النِّسَاءِ فَقُلْنَ لَهُ مَا نُقْصَانُ دِينِنَا وَعَقْلِنَا يَا رَسُولَ اللهِ؟ قَالَ أَلَيْسَ شَهَادَةُ الْمَرْأَةِ مِثْلَ نِصْفِ شَهَادَةِ الرَّجُلِ؟ قُلْنَ بَلَى قَالَ فَذَلِكَ مِنْ نُقْصَانِ عَقْلِهَا أَوَ لَيْسَ إِذَا حَاضَتِ الْمَرْأَةُ لَمْ تُصَلِّ وَلَمْ تَصُمْ فَذَلِكَ مِنْ نُقْصَانِ دِينِهَا
