Captives

It is not for a prophet to take captives until he has fully subdued the land.

8:67It is not for any prophet to have captives until he hath made slaughter in the land. Ye desire the lure of this world and Allah desireth (for you) the Hereafter, and Allah is Mighty, Wise.

O Prophet! Say to the captives in your hands: “If Allah knows goodness in your hearts, He will grant you better than what was taken from you and forgive you.

8:70O Prophet! Say unto those captives who are in your hands: If Allah knoweth any good in your hearts He will give you better than that which hath been taken from you, and will forgive you. Lo! Allah is Forgiving, Merciful.
