Imam Ahmad : 15202
حَدَّثَنَا يَزِيدُ قَالَ أَخْبَرَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ عَبَّادِ بْنِ تَمِيمٍ أَخْبَرَهُ عَنْ عُوَيْمِرِ بْنِ أَشْقَرَ أَنَّهُ ذَبَحَ قَبْلَ أَنْ يَغْدُوَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَلَمَّا صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَكَرَ ذَلِكَ لَهُ فَأَمَرَهُ أَنْ يُعِيدَ أُضْحِيَّتَهُ
Narrated to us [Yazid] said: [Yahya bin Sa'id] Narrated to us from ['Abbad bin Tamim] that He narrated to us from ['Uwaimir bin Asyqor] that he had slaughtered before the Prophet peace and blessings be upon him left for prayer. When The Messenger of Allah peace and blessings be upon him had performed the Eid prayer, this was Narrated to him, and he ordered him to repeat the slaughter.
