Sura al-Anfāl 8:70

يَٰٓأَيُّهَا ٱلنَّبِىُّ قُل لِّمَن فِىٓ أَيْدِيكُم مِّنَ ٱلْأَسْرَىٰٓ إِن يَعْلَمِ ٱللَّـهُ فِى قُلُوبِكُمْ خَيْرًا يُؤْتِكُمْ خَيْرًا مِّمَّآ أُخِذَ مِنكُمْ وَيَغْفِرْ لَكُمْ وَٱللَّـهُ غَفُورٌ رَّحِيمٌ

yā-ayyuhā l-nabiyyu qul lliman fī aydīkum mina al-asra in yaʿlami allāhu fī qulūbikum khayran yuʾtikum khayran mimmā ukhidha minkum wa-yaghfir la-kum wallāhu ghafūrun raḥīmun

O Prophet! say to those who are captives in your hands: "If Allah findeth any good in your hearts, He will give you something better than what has been taken from you, and He will forgive you: for Allah is Oft-forgiving, Most Merciful."
