Sunan Ibn Majah, Chapter: The Chapters of Establishing the Prayer and the Sunnah Regarding Them

"The Messenger of Allah (saw) used to go out on the day of Eid and lead the people in praying two Rakah, then he would say the Salam and stand on his two feet facing the people while they were sitting down. He would say: 'Give in charity. Give in charity.' Those who gave most in charity were the women, (they would give) earrings and rings and things. If he wanted to send out an expedition he would mention it, otherwise he would leave." Sahih
