(9) بَابُ قَوْلِ اللَّهِ تَعَالَى: {وَأَقْسَمُوا بِاللَّهِ جَهْدَ أَيْمَانِهِمْ}
Narrated Haritha bin Wahb:
I heard the Prophet (ﷺ) saying, "Shall I tell you of the people of Paradise? They comprise every poor humble person, and if he swears by Allah to do something, Allah will fulfill it; while the people of the fire comprise every violent, cruel arrogant person."
