Quran 3:168 from Surah Aal-i-Imraan on Divine Marvels.
ٱلَّذِينَ قَالُواْ لِإِخۡوَٰنِهِمۡ وَقَعَدُواْ لَوۡ أَطَاعُونَا مَا قُتِلُواْۗ قُلۡ فَٱدۡرَءُواْ عَنۡ أَنفُسِكُمُ ٱلۡمَوۡتَ إِن كُنتُمۡ صَٰدِقِينَ
English translation: Those who said about their brothers while they sat If they (had) obeyed us not they would have been killed Say Then avert from yourselves [the] death if you are truthful
Transliteration: alladhina qalu li-ikh'wanihim waqa'adu law ata'una ma qutilu qul fa-id'rau an anfusikumu al-mawta in kuntum sadiqina
