Jabir b. 'Abdullah reported:Allah's Messenger (ﷺ) led us in the 'Id prayer in Medina on the Day of Sacrifice. Some persons slaughtered their animals ahead of him under the impression that Allah's Apostle (ﷺ) had-already offered sacrifice. Thereupon Allah's Apostle (ﷺ) said: Those who had slaughtered their animals ahead of him should slaughter the other ones in their stead. And they should not sacrifice the animal before Allah's Messenger (ﷺ) had sacrificed (his animal)
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي أَبُو الزُّبَيْرِ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ صَلَّى بِنَا النَّبِيُّ صلى الله عليه وسلم يَوْمَ النَّحْرِ بِالْمَدِينَةِ فَتَقَدَّمَ رِجَالٌ فَنَحَرُوا وَظَنُّوا أَنَّ النَّبِيَّ صلى الله عليه وسلم قَدْ نَحَرَ فَأَمَرَ النَّبِيُّ صلى الله عليه وسلم مَنْ كَانَ نَحَرَ قَبْلَهُ أَنْ يُعِيدَ بِنَحْرٍ آخَرَ وَلاَ يَنْحَرُوا حَتَّى يَنْحَرَ النَّبِيُّ صلى الله عليه وسلم .
