'Abdullah bin 'Umar,
may Allah be pleased with them, reported: Allah's Messenger (may peace be upon him) observed: O women folk, you should give charity and ask much forgiveness for I saw you in bulk among the dwellers of Hell. A wise lady among them asked: Why is it, Messenger of Allah, that our folk is in bulk in Hell? Upon this the Holy Prophet observed: You curse too much and are ungrateful to your spouses. I have seen none lacking in common sense and failing in religion but (at the same time) robbing the wisdom of the wise besides you. Upon this the woman remarked: What is wrong with our common sense and with religion? He (the Holy Prophet) observed: Your lack of common sense (can be well judged from the fact) that the testimony of two women is equal to one man, that is a proof of the lack of common sense, and you spend some nights (and days) in which you do not offer the Prayer and in the month of Ramadan (during the days) you do not observe Fast, that is a failing in religion.

يا معشر النساء ! تصدقن وأكثرن الاستغفار . فإني رأيتكن أكثر أهل النار . فقالت امرأة منهن ، جزلة : وما لنا يا رسول الله أكثر أهل النار . قال : تكثرن اللعن . وتكفرن العشير . وما رأيت من ناقصات عقل ودين أغلب لذي لب منكن . قالت : يا رسول الله ! وما نقصان العقل والدين ؟ قال : أما نقصان العقل فشهادة امرأتين تعدل شهادة رجل . فهذا نقصان
العقل . وتمكث الليالي ما تصلي . وتفطر في رمضان . فهذا نقصان الدين
