Sura al-Baqara 2:72

وَإِذْ قَتَلْتُمْ نَفْسًا فَٱدَّٰرَْٰٔتُمْ فِيهَا وَٱللَّـهُ مُخْرِجٌ مَّا كُنتُمْ تَكْتُمُونَ

wa-idh qataltum nafsan fa-iddārāʾtum fīhā wallāhu mukhrijun mā kuntum taktumūna

Remember ye slew a man and fell into a dispute among yourselves as to the crime: But Allah was to bring forth what ye did hide.

Sura Āl-ʿImrān 3:168

ٱلَّذِينَ قَالُوا۟ لِإِخْوَٰنِهِمْ وَقَعَدُوا۟ لَوْ أَطَاعُونَا مَا قُتِلُوا۟ قُلْ فَٱدْرَءُوا۟ عَنْ أَنفُسِكُمُ ٱلْمَوْتَ إِن كُنتُمْ صَٰدِقِينَ

lladhīna qālū li-ikhwānihim wa-qaʿadū law aṭāʿūnā mā qutilū qul fa-idraʾū ʿan anfusikumu l-mawtā in kuntum ṣādiqīna

(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."
