Anas b. Malik reported:
وَحَدَّثَنِي زِيَادُ بْنُ يَحْيَى الْحَسَّانِيُّ ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ وَرْدَانَ - حَدَّثَنَا أَيُّوبُ ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ خَطَبَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَ أَضْحًى - قَالَ - فَوَجَدَ رِيحَ لَحْمٍ فَنَهَاهُمْ أَنْ يَذْبَحُوا قَالَ " مَنْ كَانَ ضَحَّى فَلْيُعِدْ " . ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِهِمَا .
Allah's Messenger (ﷺ) addressed us on the day of 'Id al-Adha. He smelt the odour of flesh and he prohibited thern from slaughtering (the animals before the 'Id prayer), saying: He who slaughtered the animals (before the 'Id prayer) should do that again (as it is not valid as a sacrifice).
