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."

Sura al-Tawbah 9:90

وَجَآءَ ٱلْمُعَذِّرُونَ مِنَ ٱلْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ ٱلَّذِينَ كَذَبُوا۟ ٱللَّـهَ وَرَسُولَهُۥ سَيُصِيبُ ٱلَّذِينَ كَفَرُوا۟ مِنْهُمْ عَذَابٌ أَلِيمٌ

wa-jāʾa l-muʿadhdhirūna mina l-aʿrābi li-yuʾdhana lahum wa-qaʿada lladhīna kadhabū allāha wa-rasūlahu sa-yuṣību lladhīna kafarū minhum ʿadhābun alīmun

And there were, among the desert Arabs (also), men who made excuses and came to claim exemption; and those who were false to Allah and His Messenger (merely) sat inactive. Soon will a grievous penalty seize the Unbelievers among them.
