Narrated Abu Mas`ud Al−Ansari: Once a man said to Allah's Apostle "O Allah's Apostle! I may not attend the (compulsory congregational) prayer because so and so (the Imam) prolongs the prayer when he leads us for it. The narrator added: "I never saw the Prophet more furious in giving advice than he was on that day. The Prophet said, "O people! Some of you make others dislike good deeds (the prayers). So whoever leads the people in prayer should shorten it because among them there are the sick, the weak and the needy (having some jobs to do).
- (Sahih Bukhari- book 3, hadith 90)

Narrated Abu Sa`id Al−Khudri: Once Allah's Apostle went out to the Musalla (to offer the prayer) of `Id−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 Allah's Apostle ?" 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 Allah's Apostle! 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."
