Quran Al-Mumtahanah 60:7

عَسَى ٱللَّهُ أَن يَجۡعَلَ بَيۡنَكُمۡ وَبَيۡنَ ٱلَّذِينَ عَادَيۡتُم مِّنۡهُم مَّوَدَّةٗۚ وَٱللَّهُ قَدِيرٞۚ وَٱللَّهُ غَفُورٞ رَّحِيمٞ

Translation

Perhaps Allāh will put, between you and those to whom you have been enemies among them, affection. And Allāh is competent, and Allāh is Forgiving and Merciful.
