حَدَّثَنَا أَسْوَدُ حَدَّثَنَا إِسْرَائِيلُ عَنْ أَبِي إِسْحَاقَ عَنْ سَعْدِ بْنِ عِيَاضٍ عَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ إِنَّ مِنْ الْبَيَانِ سِحْرًا قَالَ وَكُنَّا نَرَى أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سُمَّ فِي ذِرَاعِ شَاةٍ سَمَّتْهُ الْيَهُودُ
مسند امام احمد بن حنبل · Hadith 3777
It was narrated that 'Abdullah bin Mas'ood (RA) said; The bone (with meat attached) that was most liked by the Messenger of Allah (PBUH) was the foreleg of a sheep. He used to think that he had been poisoned with poison put in the foreleg of the sheep, and we used to think that that the Jews were the ones who poisoned him.
