Sadness and the distress that tightens the chest are at the heart of these verses. They assure that those who believe and do good, the allies of Allah and the martyrs will not grieve, and that there is no sorrow in Paradise. They urge the Prophet ﷺ not to grieve over the disbelievers’ refusal, and recall that everything happens by Allah’s decree.

[Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allāh repaid you with distress upon distress so you would not grieve for that which had escaped you [of victory and spoils of war] or [for] that which had befallen you [of injury and death]. And Allāh is [fully] Aware of what you do.
