يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَكُونُوا كَالَّذِينَ كَفَرُوا وَقَالُوا لِإِخْوَانِهِمْ إِذَا ضَرَبُوا فِي الْأَرْضِ أَوْ كَانُوا غُزًّى لَوْ كَانُوا عِنْدَنَا مَا مَاتُوا وَمَا قُتِلُوا لِيَجْعَلَ اللَّهُ ذَٰلِكَ حَسْرَةً فِي قُلُوبِهِمْ ۗ وَاللَّهُ يُحْيِي وَيُمِيتُ ۗ وَاللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ ١٥٦
O ye who believe! Be not like the Unbelievers, who say of their brethren, when they are travelling through the Earth or engaged in fighting: "If they had stayed with us, they would not have died, or been slain." This that Allah may make it a cause of sighs and regrets in their hearts. It is Allah that gives Life and Death, and Allah sees well all that ye do.
