حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ قَالَ: حَدَّثَنَا أَبُو دَاوُدَ، عَنْ زُهَيْرٍ يَعْنِي ابْنَ مُحَمَّدٍ، عَنِ أَبِي إِسْحَاقَ، عَنْ سَعْدِ بْنِ عِيَاضٍ، عَنِ ابْنِ مَسْعُودٍ قَالَ: «كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يُعْجِبُهُ الذِّرَاعُ» قَالَ: «وَسُمَّ فِي الذِّرَاعِ، وَكَانَ يَرَى أَنَّ الْيَهُودَ سَمُّوهُ»
It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: The Prophet Muhammad (peace and blessings be upon him) liked the shank (meat from the lower leg) very much. He said that it was in the shank that poison was mixed and given to the Prophet (peace and blessings be upon him), and Ibn Mas'ud (may Allah be pleased with him) believed that it was the Jews who gave the Prophet (peace and blessings be upon him) the poison.
