ٱلَّذِينَ قَالُواْ لِإِخۡوَٰنِهِمۡ وَقَعَدُواْ لَوۡ أَطَاعُونَا مَا قُتِلُواْۗ قُلۡ فَٱدۡرَءُواْ عَنۡ أَنفُسِكُمُ ٱلۡمَوۡتَ إِن كُنتُمۡ صَٰدِقِينَ ١٦٨
Those who said about their brothers while sitting [at home], "If they had obeyed us, they would not have been killed." Say, "Then prevent death from yourselves, if you should be truthful."
Translation: Saheeh International (English)
Each word's meaning and sound
Those who stayed behind from fighting, and said of their relatives who suffered on the day of Uḥud that if they had done as they said and not gone to fight then they would not have been killed, tell them, O Prophet, in reply, to keep death away from themselves when it arrives, if they are telling the truth in their claim that they would not have been killed if they had listened to them; and that the reason they themselves escaped death was because they stayed behind from fighting in Allah’s cause.
