Overall meaning :
Prophet, if you or any of the male believers intend to divorce your wives, divorce them considering their prescribed waiting period (‘iddah)—that is, when they are in a period of cleanliness from menstruation during which no intimate relations have taken place. Calculate their waiting period accurately, and fear Allah, your Lord.
Do not drive women you have revocably divorced out of their homes, nor should they themselves leave, unless they become openly guilty of immoral conduct (such as adultery). These judgements constitute the limits set by Allah; do not, therefore, transgress them. Whoever transgresses Allah’s limits has truly wronged himself. You never know, for it may well be that, after such separation, Allah may bring about something beneficial for them and make them achieve reconciliation.
When women who have been revocably divorced are about to reach the end of their waiting period, either take them back if you so wish in an honourable and fair manner or part with them in an honourable and fair manner. Call to witness two men from among Muslims who are known for their probity to witness your decision of taking your wives back. Let the witnesses give evidence according to the facts for the sake of Allah if they are asked to bear testimony. Thus is admonished everyone who believes in Allah and the Last Day (Judgement Day). For everyone who fears Allah by doing what He commands and avoiding what He forbids, Allah will make a way out of every difficulty and tight situation, and will provide for him from where he does not expect. Allah will be sufficient for everyone who puts his trust in Him and will relieve his troubles. Allah will surely accomplish His purpose. Allah has set a specific term and measure for everything.
