﴿ يَٰٓأَيُّهَا ٱلنَّبِىُّ قُل لِّمَن فِىٓ أَيْدِيكُم مِّنَ ٱلْأَسْرَىٰٓ إِن يَعْلَمِ ٱللَّهُ فِى قُلُوبِكُمْ خَيْرًۭا يُؤْتِكُمْ خَيْرًۭا مِّمَّآ أُخِذَ مِنكُمْ وَيَغْفِرْ لَكُمْ ۗ وَٱللَّهُ غَفُورٌۭ رَّحِيمٌۭ ﴾

“[Hence,] O Prophet, say unto the captives who are in your hands: "If God finds any good in your hearts, He will give you something better than all that has been taken from you, and will forgive you your sins: for God is much-forgiving, a dispenser of grace."”

(O Prophet, Say unto those captives who are in your hands) i.e. 'Abbas [Ibn 'Abd al-Muttalib]: If Allah knoweth any good) faith and sincerity (in your hearts He will give you better than that which hath been taken from you) of ransom, (and will forgive you) the sins you committed in the pre-Islamic period. (Lo! Allah is Forgiving, Merciful) towards he who believes in Him.
