Quran 8:56 from Surah Al-Anfaal on Divine Marvels.
ٱلَّذِينَ عَٰهَدتَّ مِنۡهُمۡ ثُمَّ يَنقُضُونَ عَهۡدَهُمۡ فِي كُلِّ مَرَّةٖ وَهُمۡ لَا يَتَّقُونَ
English translation: Those who you made a covenant with them then they break their covenant [in] every time and they (do) not fear (Allah)
Transliteration: alladhina ahadtta min'hum thumma yanquduna ahdahum fi kulli marratin wahum la yattaquna
