الَّذِينَ قَالُواْ لإِخْوَانِهِمْ وَقَعَدُواْ لَوْ أَطَاعُونَا مَا قُتِلُوا قُلْ فَادْرَؤُوا عَنْ أَنفُسِكُمُ الْمَوْتَ إِن كُنتُمْ صَادِقِينَ
[3:168]
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.
(They are) the ones that say, (of their brethren slain), while they themselves sit (at ease): "If only they had listened to us they would not have been slain." Say: "Avert death from your own selves, if ye speak the truth."
Those who, while they sat at home, said of their brethren (who were fighting for the cause of Allah): If they had been guided by us they would not have been slain. Say (unto them, O Muhammad): Then avert death from yourselves if ye are truthful.
