Quran 9:4 from Surah At-Tawba on Divine Marvels.
إِلَّا ٱلَّذِينَ عَٰهَدتُّم مِّنَ ٱلۡمُشۡرِكِينَ ثُمَّ لَمۡ يَنقُصُوكُمۡ شَيۡـٔٗا وَلَمۡ يُظَٰهِرُواْ عَلَيۡكُمۡ أَحَدٗا فَأَتِمُّوٓاْ إِلَيۡهِمۡ عَهۡدَهُمۡ إِلَىٰ مُدَّتِهِمۡۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلۡمُتَّقِينَ
English translation: Except those (with) whom you have a treaty among the polytheists then not they have failed you (in any) thing and not they have supported against you anyone so fulfil to them their treaty till their term Indeed Allah loves the righteous
Transliteration: illa alladhina ahadttum mina al-mush'rikina thumma lam yanqusukum shayan walam yuzahiru alaykum ahadan fa-atimmu ilayhim ahdahum ila muddatihim inna al-laha yuhibbu al-mutaqina
