Musnad Ahmed: Hadith 1982

I bear witness that the Messenger of Allah (ﷺ) prayed before the khutbah, then he delivered the khutbah. Then he thought that the women had not heard him, so he went to them, accompanied by Bilal who spread out his cloak, and he exhorted them and enjoined them to give charity, so the women started throwing - and Ayyoob [one of the narrators] pointed to his ears and his throat, as if indicating earrings and necklaces.
