At Tawbah Ayah 4

إِلَّا ٱلَّذِينَ عَـٰهَدتُّم مِّنَ ٱلْمُشْرِكِينَ ثُمَّ لَمْ يَنقُصُوكُمْ شَيْــًٔا وَلَمْ يُظَـٰهِرُواْ عَلَيْكُمْ أَحَدًا فَأَتِمُّوٓاْ إِلَيْهِمْ عَهْدَهُمْ إِلَىٰ مُدَّتِهِمْ‌ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُتَّقِينَ ٤ As for the polytheists who have honoured every term of their treaty with you and have not supported an enemy against you, honour your treaty with them until the end of its term. Surely Allah loves those who are mindful ?of Him?.
