Remarriage

When you divorce women, do not prevent them from remarrying their former husbands if they mutually agree in fairness. This is a command for those who believe in Allah and the Last Day; it is purer and more righteous for you. Allah knows, while you do not know.

2:232And when ye have divorced women and they reach their term, place not difficulties in the way of their marrying their husbands if it is agreed between them in kindness. This is an admonition for him among you who believeth in Allah and the Last Day. That is more virtuous for you, and cleaner. Allah knoweth; ye know not.

Those who declare their wives as forbidden, like their mothers, speak falsely. Their wives are not their mothers; their mothers are only those who bore them. Allah is forgiving and merciful.

58:2Such of you as put away your wives (by saying they are as their mothers) - They are not their mothers; none are their mothers except those who gave them birth - they indeed utter an ill word and a lie. And lo! Allah is Forgiving, Merciful.

Those who make such declarations and then retract must free a slave before touching their wives. This is what you are commanded. Allah is aware of what you do.

58:3Those who put away their wives (by saying they are as their mothers) and afterward would go back on that which they have said, (the penalty) in that case (is) the freeing of a slave before they touch one another. Unto this ye are exhorted; and Allah is Informed of what ye do.

If they cannot, then they must fast for two consecutive months before touching their wives. If they are unable, they must feed sixty needy people. This is to affirm your faith in Allah and His Messenger. These are the limits set by Allah, and for the deniers, there is a painful punishment.

58:4And he who findeth not (the wherewithal), let him fast for two successive months before they touch one another; and for him who is unable to do so (the penance is) the feeding of sixty needy ones. This, that ye may put trust in Allah and His messenger. Such are the limits (imposed by Allah); and for disbelievers is a painful doom.
