(But if they separate) i.e. the man and the woman through divorce, (Allah will compensate each) the man and the woman (out of His abundance) from His provision: the man will be compensated with another wife and the woman with another husband. (Allah is ever All-Embracing) in relation to them as regards marriage, (All-Knowing) of that which He prescribed for them of justice. As'ad Ibn al-Rabi' had another young wife whom he favoured, and Allah forbade him from doing so and commanded that the young and the old wives were treated equally.
