Sahih Bukhari Volume 7, Book 72, Hadith 5501

حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ ـ يَعْنِي ابْنَ الْمُخْتَارِ ـ أَخْبَرَنَا مُوسَى بْنُ عُقْبَةَ، قَالَ أَخْبَرَنِي سَالِمٌ، أَنَّهُ سَمِعَ عَبْدَ اللَّهِ، يُحَدِّثُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ لَقِيَ زَيْدَ بْنَ عَمْرِو بْنِ نُفَيْلٍ بِأَسْفَلِ بَلْدَحٍ، وَذَاكَ قَبْلَ أَنْ يُنْزَلَ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم الْوَحْىُ، فَقَدَّمَ إِلَيْهِ رَسُولُ اللَّهِ صلى الله عليه وسلم سُفْرَةً فِيهَا لَحْمٌ، فَأَبَى أَنْ يَأْكُلَ مِنْهَا، ثُمَّ قَالَ إِنِّي لاَ آكُلُ مِمَّا تَذْبَحُونَ عَلَى أَنْصَابِكُمْ، وَلاَ آكُلُ إِلاَّ مِمَّا ذُكِرَ اسْمُ اللَّهِ عَلَيْهِ‏.‏

Narrated By 'Abdullah : Allah's Apostle said that he met Zaid bin 'Amr Nufail at a place near Baldah and this had happened before Allah's Apostle received the Divine Inspiration. Allah's Apostle presented a dish of meat (that had been offered to him by the pagans) to Zaid bin 'Amr, but Zaid refused to eat of it and then said (to the pagans), "I do not eat of what you slaughter on your stone-altars (Ansabs) nor do I eat except that on which Allah's Name has been mentioned on slaughtering."
