I heard the Prophet (ﷺ) saying. "May I tell you of the people of Paradise? Every weak and poor obscure person whom the people look down upon but his oath is fulfilled by Allah when he takes an oath to do something. And may I inform you of the people of the Hell-Fire? They are all those violent, arrogant and stubborn people."
Sahih al-Bukhari Book 65, Hadith 438
← Previous Hadith (regarding the Verse):-- 'Cruel after all that, base-born (of illegitimate birth).' (68.13) It was revealed in connection with a man from Quaraish who had a notable sign (Zanamah) similar to the notable sign which usually-hung on the neck of a sheep (to recognize it).

Sahih al-Bukhari Book 65, Hadith 437 Next Hadith → I heard the Prophet (ﷺ) saying, "Our Lord Allah will lay bare His Shin, and then all the Believers, men and women, will prostrate themselves before Him, but there will remain those who used to prostrate in the world for showing off and for gaining good reputation. Such people will try to prostrate (on the Day of Judgment) but their back swill be as stiff as if it is one bone (a single vertebra).
