[Machine] Abdullah bin Busr, the companion of the Messenger of Allah ﷺ , went out with the people on the day of Eid al-Fitr or Eid al-Adha and he disapproved of the delay of the Imam. He said, "We had finished our preparations during this hour, which is the time for praising Allah. It has been narrated from Al-Hasan al-Basri that the Prophet ﷺ used to go out for Eid al-Adha and Eid al-Fitr when the sun rose a little. The Prophet ﷺ used to pray the Eid prayer in the early time. Whoever slaughtered before the Prophet's prayer and ate and fed his family and neighbors as we have been narrated in the hadith of Abu Burdah bin Niyar, his slaughter was considered invalid before its proper time, and that is not permissible. Therefore, he was commanded to repeat it. Whoever sacrifices at the proper time when the prayer is due and finishes the prayer and the sermon of the Prophet ﷺ , his sacrifice is valid, if Allah wills."  

خَرَجَ عَبْدُ اللهِ بْنُ بُسْرٍ صَاحِبُ رَسُولِ اللهِ ﷺ مَعَ النَّاسِ فِي يَوْمِ عِيدِ فِطْرٍ أَوْ أَضْحًى فَأَنْكَرَ إِبْطَاءَ الْإِمَامِ وَقَالَ إِنَّا كُنَّا فَرَغْنَا سَاعَتَنَا هَذِهِ وَذَلِكَ حِينَ التَّسْبِيحِ وَرُوِّينَا عَنِ الْحَسَنِ الْبَصْرِيِّ أَنَّ النَّبِيَّ ﷺ كَانَ يَغْدُو إِلَى الْأَضْحَى وَالْفِطْرِ حِينَ تَطْلُعُ الشَّمْسُ فَيَتَتَامُّ طُلُوعُهَا فَالنَّبِيُّ ﷺ كَانَ يُصَلِّي صَلَاةَ الْعِيدِ فِي أَوَّلِ الْوَقْتِ فَمَنْ كَانَ ذَبَحَ قَبْلَ صَلَاةِ النَّبِيِّ ﷺ وَأَكَلَ وَأَطْعَمَ أَهْلَهُ وَجِيرَانَهُ كَمَا رُوِّينَا فِي حَدِيثِ أَبِي بُرْدَةَ بْنِ نِيَارٍ كَانَ ذَبْحُهُ وَاقِعًا قَبْلَ أَنْ يَحِلَّ وَقْتُهُ وَذَلِكَ لَا يَجُوزُ فَذَلِكَ أُمِرَ بِالْإِعَادَةِ فَمَنْ ضَحَّى بِالْوَقْتِ الَّذِي يَحِلُّ فِيهِ الصَّلَاةُ وَيَمْضِي مِقْدَارُ صَلَاةِ النَّبِيِّ ﷺ وَخُطْبَتِهِ أَجْزَأَتْ أُضْحِيَّتُهُ إِنْ شَاءَ اللهُ
