If talaq is done already and after it was done, the husband decided to get back again with the wife, what should he do? Do they have to marry again or he just has to say sorry to the woman?
بسم الله الرحمن الرحيم
If you had given one or two talaq rajai to your wife then you may take her back within iddah period, i.e. you can do raja’t from her. This will require no new nikah or halalah. In case you have given three talaqs then you will have to do halalah Shariah for taking your wife back in your nikah. There is no third way except it.
Allah knows Best!
