Qur'an 8:70

يَـٰٓأَيُّهَا ٱلنَّبِىُّ قُل لِّمَن فِىٓ أَيْدِيكُم مِّنَ ٱلْأَسْرَىٰٓ إِن يَعْلَمِ ٱللَّهُ فِى قُلُوبِكُمْ خَيْرًا يُؤْتِكُمْ خَيْرًا مِّمَّآ أُخِذَ مِنكُمْ وَيَغْفِرْ لَكُمْ ۗ وَٱللَّهُ غَفُورٌ رَّحِيمٌ

O Prophet! Say unto those captives who are in your hands: If Allah knoweth any good in your hearts He will give you better than that which hath been taken from you, and will forgive you. Lo! Allah is Forgiving, Merciful.
