Divorce may be retracted twice, then the husband must retain ˹his wife˺ with honour or separate ˹from her˺ with grace.1 It is not lawful for husbands to take back anything of the dowry given to their wives, unless the couple fears not being able to keep within the limits of Allah.2 So if you fear they will not be able to keep within the limits of Allah, there is no blame if the wife compensates the husband to obtain divorce.3 These are the limits set by Allah, so do not transgress them. And whoever transgresses the limits of Allah, they are the ˹true˺ wrongdoers.
So if a husband divorces his wife ˹three times˺, then it is not lawful for him to remarry her until after she has married another man and then is divorced. Then it is permissible for them to reunite, as long as they feel they are able to maintain the limits of Allah. These are the limits set by Allah, which He makes clear for people of knowledge.
