﴿ 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."”
