Fainting

وَيَقُولُ ٱلَّذِينَ ءَامَنُوا۟ لَوْلَا نُزِّلَتْ سُورَةٌ ۖ فَإِذَآ أُنزِلَتْ سُورَةٌ مُّحْكَمَةٌ وَذُكِرَ فِيهَا ٱلْقِتَالُ ۙ رَأَيْتَ ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ يَنظُرُونَ إِلَيْكَ نَظَرَ ٱلْمَغْشِىِّ عَلَيْهِ مِنَ ٱلْمَوْتِ ۖ فَأَوْلَىٰ لَهُمْ

Those who believe ask why no sura [about fighting] has been sent down. Yet when a decisive sura [that mentions fighting] is sent down, you can see the sick at heart looking at you [Prophet] and visibly fainting at the prospect of death- better for them

طَاعَةٌ وَقَوْلٌ مَّعْرُوفٌ ۚ فَإِذَا عَزَمَ ٱلْأَمْرُ فَلَوْ صَدَقُوا۟ ٱللَّهَ لَكَانَ خَيْرًا لَّهُمْ

would be obedience and fitting words; it would also be better for them to be true to God when the decision to fight has been made.
