O Prophet, say to whoever is in your hands of the captives, (8:70)

﴿يَا أَيُّهَا النَّبِيُّ قُل لِّمَن فِي أَيْدِيكُم مِّنَ الْأَسْرَىٰ إِن يَعْلَمِ اللَّهُ فِي قُلُوبِكُمْ خَيْرًا يُؤْتِكُمْ خَيْرًا مِّمَّا أُخِذَ مِنكُمْ وَيَغْفِرْ لَكُمْ ۗ وَاللَّهُ غَفُورٌ رَّحِيمٌ﴾
[ الأنفال: 70]

8:70 O Prophet, say to whoever is in your hands of the captives, "If Allah knows [any] good in your hearts, He will give you [something] better than what was taken from you, and He will forgive you; and Allah is Forgiving and Merciful."

O Prophet, say to those idolater captives who have come into your hands after the Battle of Badr: If Allah knows of any good intentions in your hearts, He will give you something better than the ransom that was taken from you; so do not grieve over what was taken from you.
Allah will also forgive your sins because He is Forgiving and Compassionate to those of His servants who repent to Him.
This promise of Allah was fullfilled for ‘Abbās, the uncle of the Prophet ( peace be upon him ), and for others like him who accepted Islam after being captured.

O Prophet! Say to the captives that are in your hands: "If Allah knows any good in your hearts, He will give you something better than what has been taken from you, and He will forgive you, and Allah is Oft-Forgiving, Most Merciful."
