From Sahih Muslim (Hadith 1325):
A'isha, the wife of the Messenger of Allah (ﷺ) reported:The Apostle of Allah (ﷺ) used to supplicate in prayer thus:" O Allah! I seek refuge with Thee from the torment of the grave, and I seek refuge with Thee from the trial of the Masih al-Dajjal (Antichrist) and I seek refuge with Thee from the trial of life and death. O Allah! I seek refuge with Thee from sin and debt." She ('A'isha) reported: Someone said to him - (the Holy Prophet): Messenger of Allah! why is it that you so often seek refuge from debt? He said: When a (person) incurs debt, (he is obliged) to tell lies and break promise
