Musnad Ahmad 1167:36

'Abd al-Razzaq narrated to us, he said: Ma'mar informed us, he said: 'Abd Allah ibn Muslim, the brother of al-Zuhri, informed me, from a freed slave of Asma' bint Abi Bakr, from Asma', she said: I heard the Prophet, peace and blessings of Allah be upon him, saying: "Whoever among you believes in Allah and the Last Day, let her not raise her head until we raise our heads," out of dislike that they should see the 'awrahs (private parts) of the men due to the smallness of their waist-wrappers. And they were, at that time, wearing these striped garments as waist-wrappers.
