"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
