230.Then, if she is divorced for the third time (550), then that woman will not be lawful to him, until she lives (marries) with another husband (551). Then, if that second (husband) divorces her, then there is no sin on them if they re-unite (552), provided they will now observe the limits of Allah. And these are the limits of Allah, which He makes clear for those who possess knowledge.
