Abu Dawud Book 2, Hadith Number 879.

Narated By ‘Aisha, Ummul Mu’minin : The Apostle of Allah (PBUH) used to make supplication during the prayer saying: “O Allah, I seek refuge in Thee from the punishment of the grave; I seek refuge in Thee from the trial of the Antichrist; I seek refuge in Thee from the trial of life and the trial of death; O Allah, I seek refuge in Thee from sin and debt.” Someone said to him: How often you seek refuge from debt! He replied: When a man is in debt, he talks and tells lies, makes promises and breaks them.
