Abu Sa 'eed Al- Kahudri arrived from a jouney and his family offered him some meat from the sacrificial animal. He said: "I am not going to eat it until I ask about it," So he went to his half-brother through his mother, Qatadah bin An- Nu man who had been presently at Badr, and asked him about that. He said: "The opposite of what you were forbidden occurred after that, and (Permission was granted) to eat the sacrificial meat after three days" (Sahih ) (Using translation from Nasāʾī 4427)
أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ قَدِمَ مِنْ سَفَرٍ فَقَدَّمَ إِلَيْهِ أَهْلُهُ لَحْمًا مِنْ لُحُومِ الْأَضْحَى فَقَالَ مَا أَنَا بِآكِلِهِ حَتَّى أَسْأَلَ فَانْطَلَقَ إِلَى أَخِيهِ لِأُمِّهِ قَتَادَةَ بْنِ النُّعْمَانِ وَكَانَ بَدْرِيًّا فَسَأَلَهُ عَنْ ذَلِكَ فَقَالَ إِنَّهُ قَدْ حَدَثَ بَعْدَكَ أَمْرٌ نَقْضًا لِمَا كَانُوا «نُهُوا عَنْهُ مِنْ أَكْلِ لُحُومِ الْأَضْحَى بَعْدَ ثَلَاثَةِ أَيَّامٍ»
