The Messenger of Allah ﷺ used to go out on the day of 'Eid and pray two rak'ahs, then he would deliver the Khutbah and enjoin giving charity, and the ones who gave most charity were the women. If he had any exigency or he needed to send an army he would speak of that, if not, he would go back. (Using translation from Nasāʾī 1579)  

أَنَّ رَسُولَ اللهِ ﷺ «كَانَ يَخْرُجُ يَوْمَ الْعِيدِ فَيُصَلِّي رَكْعَتَيْنِ ثُمَّ يَخْطُبُ فَيَأْمُرُ بِالصَّدَقَةِ فَيَكُونُ أَكْثَرَ مَنْ يتَصَدَّقُ النِّسَاءُ فَإِنْ كَانَتْ لَهُ حَاجَةٌ أَوْ أَرَادَ أَنْ يَبْعَثَ بَعْثًا تَكَلَّمَ وَإِلَّا رَجَعَ»  

Ibn 'Abbas gave a Khutbah in Al-Basrah and said: "Pay the zakah of your fasting." The people started looking at one another. He said: "Whoever there is here from the people of Al-Madinah, get up and teach your brothers, for they do not know that the Messenger of Allah ﷺ enjoined sadaqat al-fitr on the young and the old, the free and the slave, the male and the female; half a sa' of wheat or a sa' of dried dates or barley.'" (Using translation from Nasāʾī 1580)  

أَدُّوا زَكَاةَ صَوْمِكُمْ فَجَعَلَ النَّاسُ يَنْظُرُ بَعْضُهُمْ إِلَى بَعْضٍ قَالَ مِنْ هَاهُنَا مِنْ أَهْلِ الْمَدِينَةِ قُومُوا إِلَى إِخْوَانِكُمْ فَعَلِّمُوهُمْ فَإِنَّهُمْ لَا يَعْلَمُونَ أَنَّ رَسُولَ اللهِ ﷺ «فَرَضَ صَدَقَةَ الْفِطْرِ عَلَى الصَّغِيرِ وَالْكَبِيرِ وَالْحُرِّ وَالْعَبْدِ وَالذَّكَرِ وَالْأُنْثَى نِصْفَ صَاعِ بُرٍّ وصَاعًا مِنْ تَمْرٍ أَوْ شَعِيرٍ»
