Harithah bin Wahb Al-Khuzai narrated that the Messenger Of Allah (s.a.w) said:
"Should I not inform you about the people of Paradise: They are every humble and weak person, who if he were to make an Oath by Allah, He would fulfill it. Should I not inform you about the people of the Fire: They are every prideful swaggering ill-speaking person."
