This hadith has been reported by 'Auza'i with the same chain of transmitters: We used to slaughter the camel during the lifetime of the Messenger of Allah ﷺ after the 'Asr prayer, but he made no mention of:" We used to pray along with him."

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا عِيسَى بْنُ يُونُسَ، وَشُعَيْبُ بْنُ إِسْحَاقَ الدِّمَشْقِيُّ، قَالاَ حَدَّثَنَا الأَوْزَاعِيُّ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ كُنَّا نَنْحَرُ الْجَزُورَ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ بَعْدَ الْعَصْرِ . وَلَمْ يَقُلْ كُنَّا نُصَلِّي مَعَهُ .
