48 : 4
هُوَ ٱلَّذِيٓ أَنزَلَ ٱلسَّكِينَةَ فِي قُلُوبِ ٱلۡمُؤۡمِنِينَ لِيَزۡدَادُوٓاْ إِيمَٰنٗا مَّعَ إِيمَٰنِهِمۡۗ وَلِلَّهِ جُنُودُ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۚ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمٗا
It is He Who sent down tranquility into the hearts of the believers so that they may increase in faith along with their faith. To Allah belong the soldiers of the heavens and earth. And Allah is All-Knowing, All-Wise.
