Those who believe say, "Why has a sūrah not been sent down?" But when a precise sūrah 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]
— Saheeh International
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
— M. A. S. Abdel Haleem
Those who believe say: "Why is not a Sûrah (chapter of the Qur’ân) sent down (for us)? But when a decisive Sûrah (explaining and ordering things) is sent down, and fighting (Jihâd - holy fighting in Allâh’s cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allâh and to obey Him).
