divorce in islam-question?

Yes.

"A divorce is only permissible twice: after that, the parties should either hold together on equitable terms, or separate with kindness. It is not lawful for you, (Men), to take back any of your gifts (from your wives), except when both parties fear that they would be unable to keep the limits ordained by Allah. If ye (judges) do indeed fear that they would be unable to keep the limits ordained by Allah, there is no blame on either of them if she give something for her freedom. These are the limits ordained by Allah so do not transgress them; if any do transgress the limits ordained by Allah, such persons wrong (themselves as well as others).

So if a husband divorces his wife (irrevocably), He cannot, after that, re-marry her until after she has married another husband and He has divorced her. In that case there is no blame on either of them if they re-unite, provided they feel that they can keep the limits ordained by Allah. Such are the limits ordained by Allah, which He makes plain to those who understand.

When ye divorce women and they fulfil the term of their ('Iddat), either take them back on equitable terms or set them free on equitable terms; but do not take them back to injure them, (or) to take undue advantage; if any one does that; He wrongs his own soul. Do not treat Allah's Signs as a jest, but solemnly rehearse Allah's favours on you and the fact that He sent down to you the Book and wisdom, for your instruction. And fear Allah and know that Allah is well acquainted with all things.

When ye divorce women and they fulfil the term of their ('Iddat), do not prevent them from marrying their (former) husbands, if they mutually agree on equitable terms. This instruction is for all amongst you, who believe in Allah and the Last Day. That is (the course making for) most virtue and purity amongst you and Allah knows, and ye know not."
