Al Fath Ayah 26

إِذْ جَعَلَ ٱلَّذِينَ كَفَرُواْ فِى قُلُوبِهِمُ ٱلْحَمِيَّةَ حَمِيَّةَ ٱلْجَـٰهِلِيَّةِ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَلْزَمَهُمْ كَلِمَةَ ٱلتَّقْوَىٰ وَكَانُوٓاْ أَحَقَّ بِهَا وَأَهْلَهَا‌ۚ وَكَانَ ٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمًا ٢٦ ?Remember? when the disbelievers had filled their hearts with pride—the pride of ?pre-Islamic? ignorance—then Allah sent down His serenity upon His Messenger and the believers, inspiring them to uphold the declaration of faith, for they were better entitled and more worthy of it. And Allah has ?perfect? knowledge of all things.
