The sheep which qas poisoned (and presented) to the Prophet (ﷺ) at Khaibar

Sahih al-Bukhari · Book 64 · Hadith 4249

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، حَدَّثَنِي سَعِيدٌ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ لَمَّا فُتِحَتْ خَيْبَرُ أُهْدِيَتْ لِرَسُولِ اللَّهِ صلى الله عليه وسلم شَاةٌ فِيهَا سُمٌّ‏.‏

Narrated Abu Huraira: When Khaibar was conquered, a (cooked) sheep containing poison, was given as a present to Allah's Apostle.
