8:70
يَٰٓأَيُّهَا ٱلنَّبِىُّ قُل لِّمَن فِىٓ أَيْدِيكُم مِّنَ ٱلْأَسْرَىٰٓ إِن يَعْلَمِ ٱللَّهُ فِى قُلُوبِكُمْ خَيْرًۭا يُؤْتِكُمْ خَيْرًۭا مِّمَّآ أُخِذَ مِنكُمْ وَيَغْفِرْ لَكُمْ ۗ وَٱللَّهُ غَفُورٌۭ رَّحِيمٌۭ
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."

Tafsir
Ibn Kathīr (abridged)
Pagan Prisoners at Badr were promised better than what They lost, if They become Righteous in the Future
Muhammad bin Ishaq reported that `Abdullah bin `Abbas said that before the battle of Badr, the Messenger of Allah ﷺ said,
«إِنِّي قَدْ عَرَفْتُ أَنَّ أُنَاسًا مِنْ بَنِي هَاشِمٍ وَغَيْرِهِمْ قَدْ أُخْرِجُوا كَرْهًا لَا حَاجَةَ لَهُمْ بِقِتَالِنَا فَمَنْ لَقِيَ مِنْكُمْ أَحَدًا مِنْهُمْ أَيْ مِنْ بَنِي هَاشِمٍ فَلَا يَقْتُلْهُ، وَمَنْ لَقِيَ أَبَا الْبُخْتَرِي بْنَ هِشَامٍ مُسْتَكرِهًا»
(I have come to know that some people from Bani Hashim and others were forced to accompany the pagans, although they had no desire to fight us. Therefore, whoever meets any of them (Bani Hashim), do not kill him. Whoever meets Abu Al-Bukhtari bin Hisham, should not kill him. Whoever meets Al-`Abbas bin `Abdul-Muttalib, let him not kill him, for he was forced to come (with the pagan army).) Abu Hudhayfah bin `Utbah said, "Shall we kill our fathers, children, brothers and tribesmen (from Quraysh), and leave Al-`Abbas By Allah! If I meet him, I will kill him with the sword." When this reached the Messenger of Allah ﷺ, he said to `Umar bin Al-Khattab,
«يَا أَبَا حَفْص»
(O Abu Hafs!), and `Umar said, "By Allah that was the first time that the Messenger of Allah called me Abu Hafs."
