'A'isha said, "The Prophet, may Allah bless him and grant him peace,
did something and thereby created a dispensation for doing it. Some people
still refrained from doing. The Prophet, may Allah bless him and grant
him peace, heard about that and he gave a speech and praised Allah. Then
he said, 'What is wrong with people who restrain themselves from doing
something which I do? By Allah, I know Allah better than they do and I
fear Him more than they do!'"
