Musnad Ahmad 27:894

Harun ibn Ma'ruf narrated to us, Ibn Wahb narrated to us—and once he said: Haywah—from Ibn al-Had, from Abdullah ibn Dinar, from Ibn Umar, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "O assembly of women, give charity and increase it, for I have seen that you are the majority of the people of the Fire, due to the frequency of cursing and ingratitude toward the spouse. I have not seen anyone deficient in intellect and religion who is more capable of overcoming a man of sound mind than you." She said: "O Messenger of Allah, what is the deficiency of intellect and religion?" He said: "As for the deficiency of intellect and religion: the testimony of two women is equivalent to the testimony of one man; this is the deficiency of intellect. And she remains for nights not praying and breaks her fast in Ramadan; this is the deficiency of religion."
