At-Tawbah 9:4

إِلَّا ٱلَّذِينَ عَٰهَدتُّم مِّنَ ٱلۡمُشۡرِكِينَ ثُمَّ لَمۡ يَنقُصُوكُمۡ شَيۡـٔٗا وَلَمۡ يُظَٰهِرُواْ عَلَيۡكُمۡ أَحَدٗا فَأَتِمُّوٓاْ إِلَيۡهِمۡ عَهۡدَهُمۡ إِلَىٰ مُدَّتِهِمۡۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلۡمُتَّقِينَ 4

Excepted are those with whom you made a treaty among the polytheists and then they have not been deficient toward you in anything or supported anyone against you; so complete for them their treaty until their term [has ended]. Indeed, Allah loves the righteous [who fear Him]
