The Messenger of Allah ﷺ used to go out to the prayer place on the day of Al-Fitr and the day of Al-Adha and lead the people in prayer. When he sat during the second rak'ah and said the taslim, he stood up and turned to face the people while the people were sitting. If he needed to mention something concerning the dispatch of an army he would tell the people, otherwise he would enjoin the people to give charity. He said: "Give charity" three times, and among those who gave the most charity were the women. (Using translation from Nasāʾī 1576)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَخْرُجُ يَوْمَ الْفِطْرِ وَيَوْمَ الْأَضْحَى إِلَى الْمُصَلَّى فَيُصَلِّي بِالنَّاسِ فَإِذَا جَلَسَ فِي الثَّانِيَةِ وَسَلَّمَ قَامَ فَاسْتَقْبَلَ النَّاسَ بِوَجْهِهِ وَالنَّاسُ جُلُوسٌ فَإِنْ كَانَتْ لَهُ حَاجَةٌ يُرِيدُ أَنْ يَبْعَثَ بَعْثًا ذَكَرَهُ لِلنَّاسِ وَإِلَّا أَمَرَ النَّاسَ بِالصَّدَقَةِ قَالَ «تَصَدَّقُوا تَصَدَّقُوا» ثَلَاثَ مَرَّاتٍ فَكَانَ مِنْ أَكْثَرَ مَنْ يَتَصَدَّقُ النِّسَاءُ
