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.

Those who said of their brethren whilst they (themselves) held back: Had they obeyed us, they would not have been killed. Say: Then avert death from yourselves if you speak the truth.

And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people.

When your sister went and said: Shall I direct you to one who will take charge of him? So We brought you back to your mother, that her eye might be cooled and she should not grieve and you killed a man, then We delivered you from the grief, and We tried you with (a severe) trying. Then you stayed for years among the people of Madyan; then you came hither as ordained, O Musa.

Have you not seen those who have become hypocrites? They say to those of their brethren who disbelieve from among the followers of the Book: If you are driven forth, we shall certainly go forth with you, and we will never obey any one concerning you, and if you are fought against, we will certainly help you, and Allah bears witness that they are most surely liars.
