Musnad Abu Ya'la al-Mawsili 150:241

Isma'il ibn Musa al-Suddi narrated to us, Umar ibn Sa'd al-Nasri narrated to us, from Layth, from Mujahid, from Aisha, who said: I heard the Messenger of Allah, may Allah bless him and grant him peace, saying: "Woe to the commanders, woe to the overseers (al-'urafa'), and woe to the trustees. A day will surely come upon one of them when he will wish that he were suspended by the star, and that he had not performed any work."
