Surah Aal-i-Imraan Verse 156

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَكُونُوا كَالَّذِينَ كَفَرُوا وَقَالُوا لِإِخْوَانِهِمْ إِذَا ضَرَبُوا فِي الْأَرْضِ أَوْ كَانُوا غُزًّى لَّوْ كَانُوا عِندَنَا مَا مَاتُوا وَمَا قُتِلُوا لِيَجْعَلَ اللَّهُ ذَٰلِكَ حَسْرَةً فِي قُلُوبِهِمْ ۗ وَاللَّهُ يُحْيِي وَيُمِيتُ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ

Yaaa ayyuhul lazeena aamanoo laa takoonoo kallazeena kafaroo wa qaaloo li ikhwaanihim izaa daraboo fil ardi aw kaanoo ghuzzal law kaanoo 'indanaa maa maatoo wa maa qutiloo liyaj'alal laahu zaalika hasratan fee quloobihim; qallaahu yuhyee wa yumeet; wallaahu bimaa ta'maloona Baseer

Translation / The Meaning

O you who have believed, do not be like those who disbelieved and said about their brothers when they traveled through the land or went out to fight, "If they had been with us, they would not have died or have been killed," so Allah makes that [misconception] a regret within their hearts. And it is Allah who gives life and causes death, and Allah is Seeing of what you do.
