عَنْ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ أَحَبُّ الْعُرَاقِ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الذِّرَاعَ ذِرَاعَ الشَّاةِ وَكَانَ قَدْ سُمَّ فِي الذِّرَاعِ وَكَانَ يَرَى أَنَّ الْيَهُودَ هُمْ سَمُّوهُ
Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the meat portion most beloved to the Noble Prophet (peace and blessings be upon him) was the foreleg, and specifically the foreleg of a goat. Poison was mixed into the foreleg of a goat for the Prophet (peace and blessings be upon him), and it was the Jews who gave the poison.
