"Men are overseers over women, by reason of that wherewith Allah hath made one of them excel over another, and by reason of that which they expend of their substance. Wherefore righteous women are obedient, and are watchers in husbands absence by the aid and protection of Allah. And those wives whose refractoriness ye fear, exhort them, and avoid them in beds, and beat them; but if they obey you, seek not a way against them; verily Allah is ever Lofty, Grand." - Quran 4:34 (read more)

"The interpretation of the verse "And those of your women as have passed the age of monthly courses, for them the 'Iddah (prescribed period), if you have doubt (about their periods), is three months; and for those who have no courses (i.e. they are still immature) their 'Iddah (prescribed period) is three months likewise". He said: The same applies to the 'idaah for girls who do not menstruate because they are too young, if their husbands divorce them after consummating the marriage with them." - al-Tabari
