After the waiting period of her menstruation cycle and purification has passed, if he wishes, he can take her back. If he wishes, he can divorce her.  

أَنْ يُطَلِّقَ لِلسُّنَّةِ كَمَا أَمَرَ اللهُ ﷻ فَلْيُنْظِرْهَا حَتَّى تَحِيضَ ثُمَّ تَطْهُرَ ثُمَّ لِيُطَلِّقْهَا طَاهِرًا فِي غَيْرِ جِمَاعٍ وَيُشْهِدُ رَجُلَيْنِ ثُمَّ لِيُنْظِرْهَا حَتَّى تَحِيضَ ثُمَّ تَطْهُرَ فَإِنْ شَاءَ رَاجَعَ وَإِنْ شَاءَ طَلَّقَ
