Quran 48:26 from Surah Al-Fath on Divine Marvels.
إِذۡ جَعَلَ ٱلَّذِينَ كَفَرُواْ فِي قُلُوبِهِمُ ٱلۡحَمِيَّةَ حَمِيَّةَ ٱلۡجَٰهِلِيَّةِ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلۡمُؤۡمِنِينَ وَأَلۡزَمَهُمۡ كَلِمَةَ ٱلتَّقۡوَىٰ وَكَانُوٓاْ أَحَقَّ بِهَا وَأَهۡلَهَاۚ وَكَانَ ٱللَّهُ بِكُلِّ شَيۡءٍ عَلِيمٗا
English translation: When had put those who disbelieved in their hearts disdain (the) disdain (of) the time of ignorance Then Allah sent down Then Allah sent down His tranquility upon His Messenger and upon the believers and made them adhere (to the) word (of) righteousness and they were more deserving of it and worthy of it And is Allah of every thing All-Knower
