يَٰٓأَيُّهَا ٱلنَّبِيُّ قُل لِّمَن فِيٓ أَيۡدِيكُم مِّنَ ٱلۡأَسۡرَىٰٓ إِن يَعۡلَمِ ٱللَّهُ فِي قُلُوبِكُمۡ خَيۡرٗا يُؤۡتِكُمۡ خَيۡرٗا مِّمَّآ أُخِذَ مِنكُمۡ وَيَغۡفِرۡ لَكُمۡۚ وَٱللَّهُ غَفُورٞ رَّحِيمٞ ٧٠
O Prophet, say to whoever is in your hands of the captives, "If Allāh knows [any] good in your hearts, He will give you [something] better than what was taken from you, and He will forgive you; and Allāh is Forgiving and Merciful."
Translation: Saheeh International (English)
Each word's meaning and sound
O Prophet, say to those idolater captives who have come into your hands after the Battle of Badr: If Allah knows of any good intentions in your hearts, He will give you something better than the ransom that was taken from you; so do not grieve over what was taken from you. Allah will also forgive your sins because He is Forgiving and Compassionate to those of His servants who repent to Him. This promise of Allah was fullfilled for ‘Abbās, the uncle of the Prophet (peace be upon him), and for others like him who accepted Islam after being captured.
