Harithah ibn Wahb reported: The Prophet, peace and blessings be upon him, said,
“Shall I not tell you about the inhabitants of Paradise? Every meek, humble person, but if they swore an oath by Allah, he would fulfill it.
Shall I not tell you about the inhabitants of Hellfire? Every cruel, rude, and arrogant person.”
