Al-Adab Al-Mufrad #438

'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!'"
