يا أَيُّهَا الَّذينَ آمَنوا لا تَكونوا كَالَّذينَ كَفَروا وَقالوا لِإِخوانِهِم إِذا ضَرَبوا فِي الأَرضِ أَو كانوا غُزًّى لَو كانوا عِندَنا ما ماتوا وَما قُتِلوا لِيَجعَلَ اللَّهُ ذٰلِكَ حَسرَةً في قُلوبِهِم ۗ وَاللَّهُ يُحيي وَيُميتُ ۗ وَاللَّهُ بِما تَعمَلونَ بَصيرٌ

O you who believe, don’t be like those who disbelieve, speaking of their brethren who marched in the land, or went on the offensive, “Had they stayed with us, they wouldn’t have died or been killed.” God makes this a source of regret in their hearts. God gives life and brings death, and God is observant of what you do.
