It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "O group of women! Give charity in abundance, for I have seen that you form the majority of the inhabitants of Hell. This is because of your frequent cursing and your disobedience to your husbands. I have not seen any deficient in religion and intellect more overwhelming to a wise man than you. A woman asked: O Messenger of Allah! What is meant by deficiency in religion and intellect? The Prophet (peace and blessings be upon him) said: 'The fact that the testimony of two women is equal to that of one man is a sign of deficiency in intellect, and the inability to pray and fast for several days (during menstruation) is a sign of deficiency in religion.'"
