230th Ayah from Surah Al Baqarah
Sahih International
And if he has divorced her [for the third time], then she is not lawful to him afterward until [after] she marries a husband other than him. And if the latter husband divorces her [or dies], there is no blame upon the woman and her former husband for returning to each other if they think that they can keep [within] the limits of Allah . These are the limits of Allah, which He makes clear to a people who know.
Abdul Haleem
If a husband re-divorces his wife after the second divorce, she will not be lawful for him until she has taken another husband; if that one divorces her, there will be no blame if she and the first husband return to one another, provided they feel that they can keep within the bounds set by God. These are God’s bounds, which He makes clear for those who know.
Mohsin Khan/Hilali
And if he has divorced her (the third time), then she is not lawful unto him thereafter until she has married another husband. Then, if the other husband divorces her, it is no sin on both of them that they reunite, provided they feel that they can keep the limits ordained by Allah. These are the limits of Allah, which He makes plain for the people who have knowledge.
Taqi Usmani
Thereafter, if he divorces her, she shall no longer remain lawful for him unless she marries a man other than him. Should he too divorce her, then there is no sin on them in their returning to each other, if they think they would maintain the limits set by Allah. These are the limits set by Allah that He makes clear to a people who know (that Allah is alone capable of setting these limits).
