The full narration
Abu Huraira reported that when this verse was revealed:"Whoever does evil will be requited for it", and when this was conveyed to the Muslims they were greatly perturbed. Thereupon Allah's Messenger (ﷺ) said: Be moderate and stand firm in trouble that falls to the lot of a Muslim (as that) is an expiation for him; even stumbling on the path or the pricking of a thorn (are an expiation for him). Muslim said that 'Umar b. Abd al-Rahman Muhaisin was from amongst the people of Mecca
