﴿ وَإِن يَتَفَرَّقَا يُغْنِ ٱللَّهُ كُلًّۭا مِّن سَعَتِهِۦ ۚ وَكَانَ ٱللَّهُ وَٰسِعًا حَكِيمًۭا ﴾

“And if husband and wife do separate, God shall provide for each of them out of His abundance: for God is indeed infinite, wise,”

(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.
