Volume 3, Book 41, Number 582:
Narrated ‘Aisha:
Allah’s Apostle used to invoke Allah in the prayer saying, “O Allah, I seek refuge with you from all
sins, and from being in debt.” Someone said, O Allah’s Apostle! (I see you) very often you seek refuge
with Allah from being in debt. He replied, “If a person is in debt, he tells lies when he speaks, and
breaks his promises when he promises.”
