Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) delivered the sermon after the Eid prayer, then came to the women, because he thought that his voice had not reached them; Sayyiduna Bilal (may Allah be pleased with him) was with him. He (peace and blessings be upon him) admonished the women and commanded them to give charity, so the women began dropping their rings and earrings into a cloth, and Sayyiduna Bilal (may Allah be pleased with him) was holding that cloth. One hadith has these words: "The Messenger of Allah (peace and blessings be upon him) went out to the prayer ground on the day of Eid al-Fitr, led two rak'ahs of prayer, then delivered the sermon, then came to the women and told them to give charity, and Sayyiduna Bilal (may Allah be pleased with him) was with him, and they began dropping their jewellery."
