Surah Al-Fath 48:26

إِذْ جَعَلَ ٱلَّذِينَ كَفَرُوا۟ فِى قُلُوبِهِمُ ٱلْحَمِيَّةَ حَمِيَّةَ ٱلْجَـٰهِلِيَّةِ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَلْزَمَهُمْ كَلِمَةَ ٱلتَّقْوَىٰ وَكَانُوٓا۟ أَحَقَّ بِهَا وَأَهْلَهَا ۚ وَكَانَ ٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمًا

And ever is Allāh, of all things, Knowing.
