The Book of Prayer
وَعَنِ ابْنِ بُرَيْدَةَ, عَنْ أَبِيهِ قَالَ: { كَانَ النَّبِيُّ - صلى الله عليه وسلم -لَا يَخْرُجُ يَوْمَ اَلْفِطْرِ حَتَّى يَطْعَمَ, وَلَا يَطْعَمُ يَوْمَ اَلْأَضْحَى حَتَّى يُصَلِّيَ } رَوَاهُ أَحْمَدُ, وَاَلتِّرْمِذِيُّ, وَصَحَّحَهُ ابْنُ حِبَّانَ [1] .
Narrated Ibn Buraidah on the authority of his father: Allah's Messenger (ﷺ) would not go out on the day of breaking of the fast till he had some food, and he would not to take any food on the day of sacrifice till he had prayed (the 'Eid prayer). [Reported by Ahmad and at-Tirmidhi; Ibn Hibban graded it Sahih (authentic)].
