A Jewess brought a poisoned (cooked) sheep for the Prophet ﷺ who ate from it. She was brought to the Prophet and he was asked, "Shall we kill her?" He said, "No." I continued to see the effect of the poison on the palate of the mouth of Messenger of Allah ﷺ .  

أَنَّ يَهُودِيَّةً أَتَتِ النَّبِيَّ ﷺ بِشَاةٍ مَسْمُومَةٍ فَأَكَلَ مِنْهَا فَجِيءَ بِهَا فَقِيلَ أَلاَ نَقْتُلُهَا قَالَ لاَ فَمَا زِلْتُ أَعْرِفُهَا فِي لَهَوَاتِ رَسُولِ اللَّهِ ﷺ
