At the end of the verse...
At the end of the verse, it points to the whole of the ordinances that are stated in this verse, and says: "...Those are Allah's limits; so do not transgress them. And, whoever transgresses Allah's limits -then these are they that are the (willful) wrongdoers." Messages 1- Plurality of divorce is based on plurality of marriage, i.e. there should be a marriage before a divorce.
When a man, in one session, tells his wife: 'I divorced you thrice', there has occurred, indeed one divorce, because he has not ceased more than one marriage. For this reason, in the jurisprudence of Ahlul-Bayt (as) it is cited that a number of divorces should be fulfilled in a number of stages; and before every divorce there should also be wedlock. This plurality, besides the apparent indication of the verse, is for a closer common good, too.
It is not convenient that the relation of a family be disturbed in one gathering and by one decision for ever. 2- Earning the life by the husband and obedience of the wife unto her husband are the limits of Allah. 3- The breaker of the law is unjust.
"If he divorces her (for the third time), she shall not be lawful to him thereafter, until she marries another husband; and if he (the latter) divorces her, then it is no sin on (either of) them to return to each other (by marriage), if they think that they can keep Allah's bounds.
Those are Allah's limits; He makes them clear to a people who know." Occasion of Revelation Once, at the time of Prophet of Islam (S) , a woman came to him and said she had been the spouse of her cousin by the name of Rifa'ah, who divorced her thrice. After that, she married a man named, Abd-ur-Rahman, but he, before any sexual relations with her, divorced her, too. Then, she asked the Prophet (S) whether she could return to her first husband.
The Messenger of Allah (S) did not agree and said that her marriage with that first husband was right if she had sexual intercourse with her new husband. The above verse was revealed.
