Musnad Ahmad 32:535

Hassan narrated to us, Ibn Lahi'ah narrated to us, from Abu al-Nadr, from Anas ibn Malik, from the Prophet, peace and blessings of Allah be upon him, that he said: "Shall I not inform you of the people of the Fire and the people of the Paradise? As for the people of the Paradise, they are every weak person who is deemed weak, disheveled, wearing two tattered garments; if he were to swear by Allah, He would fulfill it for him. And as for the people of the Fire, they are every arrogant, greedy, hoarding, stingy person, who possesses followers."
