talaq e ahsan

Talaq-e-Ahsan" is the 'most proper' form of talaq in which the husband expresses divorce in single sentence - "I have divorced thee" - during the period of tuhr (when the wife is not menstruating) and then has to wait till the iddat period is over. Iddat period for a woman who has been divorced by her husband is usually three monthly periods and during this time, she cannot marry another man. If before the completion of iddat, the husband resumes co-habitation with his wife or says that "I have retained thee", the divorce is revoked.
