Surah Muhammad (Muhammad), Verse 20

وَیَقُوْلُ الَّذِیْنَ اٰمَنُوْا لَوْلَا نُزِّلَتْ سُوْرَةٌ فَاِذَاۤ اُنْزِلَتْ سُوْرَةٌ مُّحْكَمَةٌ وَّذُكِرَ فِیْهَا الْقِتَالُ رَاَیْتَ الَّذِیْنَ فِیْ قُلُوْبِهِمْ مَّرَضٌ یَّنْظُرُوْنَ اِلَیْكَ نَظَرَ الْمَغْشِیِّ عَلَیْهِ مِنَ الْمَوْتِ فَاَوْلٰى لَهُمْ ۟

Wa yaqoolul lazeena aamanoo law laa nuzzilat Sooratun fa izaaa unzilat Sooratum Muhkamatunw wa zukira feehal qitaalu ra aytal lazeena fee quloobihim maraduny yanzuroona ilaika nazaral maghshiyyi 'alaihi minal mawti fa'awlaa lahum

“Those who believe say, "Why is not a sura sent down (for us)?" But when a sura of basic or categorical meaning is revealed, and fighting is mentioned therein, thou wilt see those in whose hearts is a disease looking at thee with a look of one in swoon at the approach of death. But more fitting for them-”
