My wife converted as Islam and applied for divorce...

Praise be to Allah, god of the worlds, and prayers and peace be upon His faithful Messenger, and after: you have to know Allah guides you that it is not permissible for a woman Muslim to remain on the authority of a non-Muslim man and must distinguish between them immediately,

The Almighty said: (O you who have believed, when the believing women come to you as emigrants, examine [i.e., test] them. Allāh is most knowing as to their faith. And if you know them to be believers, then do not return them to the disbelievers; they are not lawful [wives] for them, nor are they lawful [husbands] for them. But give them [i.e., the disbelievers] what they have spent.[1676] And there is no blame upon you if you marry them when you have given them their due compensation [i.e., mahr]. And hold not to marriage bonds with disbelieving women, but ask for what you have spent and let them [i.e., the disbelievers] ask for what they have spent. That is the judgement of Allāh; He judges between you. And Allāh is Knowing and Wise)

But do not marry someone else until her period is over and the judge gives him the period of menstruation, so the husband’s safest Islam returns it to him, otherwise he separates them and never permits him until he enters Islam

Allah knows best and wisest.

It is irreversible to you unless you convert to Islam.

We advise you from this site to enter into the religion of ِAllah Almighty and to believe in Allah that is the one Creator who is unique in worship and that he is capable of everything and has sent his prophets to guide people like Ibrahim, Moses and Jesus, peace be upon them then he sealed them with Muhammad, may God bless him and grant him peace, and the Holy Qur’an gave him an eternal miracle that has not changed and has not been changed.

We ask Allah to guide you to Islam.
