The Prophet ﷺ said, "Shall I tell you about the people of Paradise? Every weak person who is regarded as weak, yet if he were to swear an oath by Allah, Allah would fulfill it for him. Shall I tell you about the people of the Fire? Every harsh, greedy, arrogant person."
عن النبي ﷺ قال: ألا أخبركم بأهل الجنة؟ كل ضعيف متضعف، لو أقسم على الله لأبره. ألا أخبركم بأهل النار؟ كل عتل جواظ مستكبر.
Bukhari narrated it in Al-Adab (6071), and Muslim in Al-Jannah (2853), both through the route of Mabad bin Khalid Qaysi, from Haritha bin Wahb Khuzai, who mentioned it.There are other hadiths with similar meaning mentioned in the description of Paradise and Hellfire.
