The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 1924
Ibn 'Abbas reported: I bear testimony to the Messenger of Allah (may peace be upon him) offering prayer before Kbutba. He (after saying prayer) delivered the Kutba, and he found that the women could not hear it, so he came to them and exhorted them and preached them and commanded them to give alms, and Bilal had stretched his cloth and the women were throwing rings, earrings and other things. This hadith has been narrated on the authority of Ayyub with the same chain of transmitters.
