حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ حَدَّثَنَا زُهَيْرٌ حَدَّثَنَا الْأَسْوَدُ بْنُ قَيْسٍ ح و حَدَّثَنَاه يَحْيَی بْنُ يَحْيَی أَخْبَرَنَا أَبُو خَيْثَمَةَ عَنْ الْأَسْوَدِ بْنِ قَيْسٍ حَدَّثَنِي جُنْدَبُ بْنُ سُفْيَانَ قَالَ شَهِدْتُ الْأَضْحَی مَعَ رَسُولِ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ فَلَمْ يَعْدُ أَنْ صَلَّی وَفَرَغَ مِنْ صَلَاتِهِ سَلَّمَ فَإِذَا هُوَ يَرَی لَحْمَ أَضَاحِيَّ قَدْ ذُبِحَتْ قَبْلَ أَنْ يَفْرُغَ مِنْ صَلَاتِهِ فَقَالَ مَنْ کَانَ ذَبَحَ أُضْحِيَّتَهُ قَبْلَ أَنْ يُصَلِّيَ أَوْ نُصَلِّيَ فَلْيَذْبَحْ مَکَانَهَا أُخْرَی وَمَنْ کَانَ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِ اللَّهِ
صحیح مسلم · Hadith 5064
Jundab b. Sufyan reported: I was with Allah's Messenger ( صلی اللہ علیہ وسلم ) on the day of 'Id al-Adha. While he had not returned after having offered (the Id prayer) and finished it, he saw the flesh of the sacrificial animals which had been slaughtered before he had completed the prayer. Thereupon he (the Holy Prophet) said: One who slaughtered his sacrificial animal before his prayer or our prayer ('Id), he should slaughter another one in its stead, and he who did not slaughter, he should slaughter by reciting the name of Allah.
