"The Prophet would not leave on the Day of Fitr until he ate, and he would not eat on the day of Adha until he prayed."  

كَانَ النَّبِيُّ ﷺ لاَ يَخْرُجُ يَوْمَ الْفِطْرِ حَتَّى يَطْعَمَ وَلاَ يَطْعَمُ يَوْمَ الأَضْحَى حَتَّى يُصَلِّيَ قَالَ وَفِي الْبَابِ عَنْ عَلِيٍّ وَأَنَسٍ  

"The Prophet would have a breakfast of dates on the Day of Fitr before leaving for the Musalla."  

أَنَّ النَّبِيَّ ﷺ كَانَ يُفْطِرُ عَلَى تَمَرَاتٍ يَوْمَ الْفِطْرِ قَبْلَ أَنْ يَخْرُجَ إِلَى الْمُصَلَّى
