Translation for 3:156

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَكُونُواْ كَٱلَّذِينَ كَفَرُواْ وَقَالُواْ لِإِخۡوَٰنِهِمۡ إِذَا ضَرَبُواْ فِي ٱلۡأَرۡضِ أَوۡ كَانُواْ غُزّٗى لَّوۡ كَانُواْ عِندَنَا مَا مَاتُواْ وَمَا قُتِلُواْ لِيَجۡعَلَ ٱللَّهُ ذَٰلِكَ حَسۡرَةٗ فِي قُلُوبِهِمۡۗ وَٱللَّهُ يُحۡيِۦ وَيُمِيتُۗ وَٱللَّهُ بِمَا تَعۡمَلُونَ بَصِيرٞ ١٥٦
O believers! Do not be like the unfaithful1 who say about their brothers who travel throughout the land or engage in battle, “If they had stayed with us, they would not have died or been killed.” Allah makes such thinking a cause of agony in their hearts. It is Allah who gives life and causes death. And Allah is All-Seeing of what you do.
