Narrator:Jundab ibn Abdullah
حَدَّثَنَا مُسْلِمٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الأَسْوَدِ، عَنْ جُنْدَبٍ، قَالَ
صَلَّى النَّبِيُّ صلى الله عليه وسلم يَوْمَ النَّحْرِ ثُمَّ خَطَبَ، ثُمَّ ذَبَحَ فَقَالَ " مَنْ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيَذْبَحْ أُخْرَى مَكَانَهَا، وَمَنْ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِ اللَّهِ "
Jundub ibn ‘Abdullāh al-Bajali (may Allah be pleased with him) reported that the Messenger (may Allah's peace and blessings be upon him) prayed on the Day of Nahr, then delivered a sermon, then slaughtered (an animal) and said: "Whoever slaughtered before praying should slaughter another animal instead, and whoever has not yet slaughtered should slaughter while mentioning Allah's name."
