يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَكُونُواْ كَٱلَّذِينَ كَفَرُواْ وَقَالُواْ لِإِخْوَٲنِهِمْ إِذَا ضَرَبُواْ فِى ٱلْأَرْضِ أَوْ كَانُواْ غُزًّى لَّوْ كَانُواْ عِندَنَا مَا مَاتُواْ وَمَا قُتِلُواْ لِيَجْعَلَ ٱللَّهُ ذَٲلِكَ حَسْرَةً فِى قُلُوبِهِمْۗ وَٱللَّهُ يُحْىِۦ وَيُمِيتُۗ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ ١٥٦
O believers! Do not be like the unfaithful 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
