وَيَقُوْلُ الَّذِيْنَ اٰمَنُوْا لَوْلَا نُزِّلَتْ سُوْرَةٌ ۚفَاِذَآ اُنْزِلَتْ سُوْرَةٌ مُّحْكَمَةٌ وَّذُكِرَ فِيْهَا الْقِتَالُ ۙرَاَيْتَ الَّذِيْنَ فِيْ قُلُوْبِهِمْ مَّرَضٌ يَّنْظُرُوْنَ اِلَيْكَ نَظَرَ الْمَغْشِيِّ عَلَيْهِ مِنَ الْمَوْتِۗ فَاَوْلٰى لَهُمْۚ ( محمد: ٢٠ )

Sahih International:
Those who believe say, "Why has a Surah not been sent down?" But when a precise Surah is revealed and battle is mentioned therein, you see those in whose hearts is disease [i.e., hypocrisy] looking at you with a look of one overcome by death. And more appropriate for them [would have been] (Muhammad [47] : 20)
1 Mufti Taqi Usmani
And the believers say, “Why has a (new) Sūrah not been revealed?” Then, once an operative Sūrah is sent down, and fighting (in Allah’s way) is mentioned in it, you notice those who have disease in their hearts, looking to you like one who is faint because of death. So, destruction is very close to them.
