If we don't make qurban or don't have qurban animals to eat at Eid al-Adha, is it still advisable to eat (breakfast) before Eid al-Adha prayers?
From 'Abdullah bin Buraidah, from his father, he said,
كَانَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- لاَ يَغْدُو يَوْمَ الْفِطْرِ حَتَّى يَأْكُلَ وَليه وسلم- لاَ يَغْدُو يَوْمَ الْفِطْرِ حَتَّى يَأْكُلَ وَلاَ يَأْكُلُ عيَن
"The Messenger of Allah -peace and prayer of Allah be upon him- used to go to the 'Ied prayer on the day of Eid al-Fithri and he ate first. Meanwhile, on the day of Eid al-Adha, he does not eat first, except after returning from the 'Ied prayer, then he will eat the results of his qurban. " (Narrated by Ahmad, 5: 352. Shaykh Syu'aib Al-Arnauth said that this hadith is hasan).
People who go to the id prayer cannot be separated from two possibilities, having qurban animals, not having sacrificial animals.
First, who has a sacrificial animal, agreed the scholars, it is sunnah for him to postpone eating on Eid al-Adha. It is recommended that he later break the fast by eating the heart of his qurban animal. This is based on the hadith from Buraidah radhiyallahu 'anhu, he said,
وَكَانَ إِذَا رَجَعَ أَكَلَ مِنْ كَبِدِ أُضْحِيَتِهِ
"When the Prophet sallallaahu 'alaihi wa sallam returns, he will eat from the heart of his sacrificial animal." (Narrated by Al-Baihaqi in As-Sunan Al-Kubra, 3: 283)
Second, who do not have qurban animals, jumhur ulama (majority of ulama: Hanafiyah ulama, Malikiyah ulama, an expression of Shafi'iyah), are praised to continue to postpone eating (until the id prayer).
Meanwhile, the scholars of Hambali, for those who do not have qurban animals, it is okay to eat before prayer or after. From the Buraidah hadith mentioned above, the scholar Hambali said that if you don't have a sacrificial animal, it is okay to eat beforehand.
