The verse: "Then give those whose wives have gone"

Masruq (may Allah have mercy on him) said: When a woman went over to the polytheists, her husband would be given the equivalent of her dowry. And when a woman went over to a people of the polytheists with whom there was no covenant, and you then had your turn and gained booty, "then give those whose wives have gone the like of what they had spent" [Al-Mumtahanah: 11], meaning: give her husband, from the booty, the equivalent of her dowry.

The like of this is also narrated through another chain.
