Narrated Aisha:
That her father (Abu Bakr) never broke his oath till Allah revealed the order of the legal expiation
for oath. Abu Bakr said, "If I ever take an oath (to do something) and later find that to do something
else is better, then I accept Allah's permission and do that which is better, (and do the legal expiation
for my oath ) ".
