يَا أَيُّهَا الَّذِينَ آمَنُواْ لاَ تَكُونُواْ كَالَّذِينَ كَفَرُواْ وَقَالُواْ لإِخْوَانِهِمْ إِذَا ضَرَبُواْ فِي الأَرْضِ أَوْ كَانُواْ غُزًّى لَّوْ كَانُواْ عِندَنَا مَا مَاتُواْ وَمَا قُتِلُواْ لِيَجْعَلَ اللّهُ ذَلِكَ حَسْرَةً فِي قُلُوبِهِمْ وَاللّهُ يُحْيِـي وَيُمِيتُ وَاللّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
[3:156]
O you who believe! be not like those who disbelieve and say of their brethren when they travel in the earth or engage in fighting: Had they been with us, they would not have died and they would not have been slain; so Allah makes this to be an intense regret in their hearts; and Allah gives life and causes death and Allah sees what you do.
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.
O ye who believe! Be not as those who disbelieved and said of their brethren who went abroad in the land or were fighting in the field: If they had been (here) with us they would not have died or been killed: that Allah may make it anguish in their hearts. Allah giveth life and causeth death; and Allah is Seer of what ye do.
