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

“But excepted shall be -from among those who ascribe divinity to aught beside God - [people] with whom you [O believers] have made a covenant and who thereafter have in no wise failed to fulfil their obligations towards you, and neither have aided anyone against you: observe, then, your covenant with them until the end of the term agreed with them. Verily, God loves those who are conscious of Him.”

(Excepting those of the idolaters with whom ye (Muslims) have a treaty) i.e. the Banu Kinanah after the year of al-Hudaybiyyah, (and who have since abated nothing of your right) who they did not break their treaties, i.e. those who had a nine month treaty (nor have supported anyone) of your enemies (against you. (As for these), fulfil their treaty to them till their term) i.e. nine months. (Lo! Allah loveth those who keep their duty (unto Him)) by not breaking their treaties.
