232nd Ayah from Surah Al Baqarah
Sahih International
And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they agree among themselves on an acceptable basis. That is instructed to whoever of you believes in Allah and the Last Day. That is better for you and purer, and Allah knows and you know not.
Abdul Haleem
When you divorce women and they have reached their set time, do not prevent them from remarrying their husbands if they both agree to do so in a fair manner. Let those of you who believe in God and the Last Day take this to heart: that is more wholesome and purer for you. God knows and you do not.
Mohsin Khan/Hilali
And when you have divorced women and they have fulfilled the term of their prescribed period, do not prevent them from marrying their (former) husbands, if they mutually agree on reasonable basis. This (instruction) is an admonition for him among you who believes in Allah and the Last Day. That is more virtuous and purer for you. Allah knows and you know not.
Taqi Usmani
When you have divorced women, and they have reached (the end of) their waiting period, do not prevent them from marrying their husbands when they mutually agree with fairness. Thus the advice is given to everyone of you who believes in Allah and in the Hereafter. This is more pure and clean for you. Allah knows and you do not know.
