Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "O Abu al-Darda'! Shall I not tell you about the people of Hell?" I said: Yes! O Messenger of Allah! He said: "Every ill-tempered, self-conceited, arrogant person who hoards wealth and does not give (in the path of Allah). Shall I not tell you about the people of Paradise? Every poor person who, if he swears an oath by Allah, Allah Almighty fulfils it for him."
Imam al-Tabarani recorded it; its chain contains a narrator, Kharijah bin Mus'ab, and he is matruk (abandoned).
