Majma al-Zawaid 17916 — One who is paid no attention

Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: We were with the Prophet (peace and blessings be upon him) at a funeral, and he said: "Shall I not tell you about the worst of Allah's servants? Every harsh and arrogant person. Shall I not tell you about the best of Allah's servants? Every weak person of lowly standing whose clothing is ordinary, who is not paid any attention, but (his state is such that) if he swears an oath by Allah, Allah Almighty fulfils it for him."
Imam Ahmad recorded it; its chain contains a narrator, Muhammad bin Jabir, who has been declared trustworthy despite his weakness. The remaining narrators of this report are the narrators of the Sahih.
