3:156

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

Word by Word:

O you who believe[d]! (Do) not be like those who disbelieved and they said about their brothers when they traveled in the earth or they were fighting, "If they had been with us, they (would) not (have) died and not they would have been killed." So Allah makes that a regret in their hearts. And Allah gives life and causes death, and Allah of what you do (is) All-Seer.

Translations:

O you who have attained to faith! Be not like those who are bent on denying the truth and say of their brethren [who die] after having set out on a journey to faraway places or gone forth to war, "Had they but remained with us, they would not have died," or, "they would not have been slain" - for God will cause such thoughts to become a source of bitter regret in their hearts, since it is God who grants life and deals death. And God sees all that 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 God may make it a caus e of sighs and regrets in their hearts. It is God that gives Life and Death, and God 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.

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, or been slain; that Allah may make it to be a regret in their hearts. And Allah gives life and causes death. And Allah is Seer of what you do.

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.
