Qur'an 9:4 · At-Tawba

إِلَّا ٱلَّذِينَ عَٰهَدتُّم مِّنَ ٱلْمُشْرِكِينَ ثُمَّ لَمْ يَنقُصُوكُمْ شَيْـًۭٔا وَلَمْ يُظَٰهِرُوا۟ عَلَيْكُمْ أَحَدًۭا فَأَتِمُّوٓا۟ إِلَيْهِمْ عَهْدَهُمْ إِلَىٰ مُدَّتِهِمْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُتَّقِينَ

(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, Allāh loves the righteous [who fear Him].
