1465. hadíth
وَ كَانَ عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ يَأْكُلُ يَوْمَ اَلْفِطْرِ قَبْلَ أَنْ يَغْدُوَ إِلَى اَلْمُصَلَّى وَ لاَ يَأْكُلُ يَوْمَ اَلْأَضْحَى حَتَّى يَذْبَحَ.
Imam Ali (a.s) would eat on the day of Eid al-Fitr before heading to the prayer area, but on the day of Eid al-Adha, he would not eat until after performing the ritual sacrifice.
