If you are in doubt, the period of waiting will be three months for those women who have ceased menstruating and for those who have not [yet] menstruated; the waiting period of those who are pregnant will be until they deliver their burden: God makes things easy for those who are mindful of Him.
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, except in case of death]. And for those who are pregnant (whether they are divorced or their husbands are dead), their ‘Iddah (prescribed period) is until they lay down their burden; and whosoever fears Allâh and keeps his duty to Him, He will make his matter easy for him.
