Urwah bin al-Zubayr (may Allah have mercy on him) said that Sayyidah Aishah (may Allah be pleased with her) informed him that the Messenger of Allah (peace and blessings be upon him) used to supplicate in the prayer: 'Allahumma inni a'udhu bika minal-ma'thami wal-maghram' (O Allah, I seek refuge in You from sin and from debt). Sayyidah Aishah (may Allah be pleased with her) said: Someone said: How often you seek refuge from debt! He (peace and blessings be upon him) said: "When a man falls into debt, he speaks and lies, and he promises and breaks his promise."
