ٱلَّذِينَ قَالُوا۟ لِإِخْوَٰنِهِمْ وَقَعَدُوا۟ لَوْ أَطَاعُونَا مَا قُتِلُوا۟ ۗ قُلْ فَٱدْرَءُوا۟ عَنْ أَنفُسِكُمُ ٱلْمَوْتَ إِن كُنتُمْ صَٰدِقِينَ
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.
Surah Aal-i-Imraan(3:168)
