Narrated Anas bin Malik:

A Jewess brought a poisoned sheep to the Messenger of Allah ﷺ, and he ate of it. She was then brought to the Messenger of Allah ﷺ who asked her about it. She said: I intended to kill you. He said: Allah will not give you control over it ; or he said : over me. They (the Companions) said: Should we not kill her ? He said: No. He (Anas) said: I always found it in the uvula of the Messenger of Allah ﷺ

حَدَّثَنَا يَحْيَى بْنُ حَبِيبِ بْنِ عَرَبِيٍّ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا شُعْبَةُ، عَنْ هِشَامِ بْنِ زَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ امْرَأَةً، يَهُودِيَّةً أَتَتْ رَسُولَ اللَّهِ ﷺ بِشَاةٍ مَسْمُومَةٍ فَأَكَلَ مِنْهَا فَجِيءَ بِهَا إِلَى رَسُولِ اللَّهِ ﷺ فَسَأَلَهَا عَنْ ذَلِكَ فَقَالَتْ أَرَدْتُ لأَقْتُلَكَ . فَقَالَ " مَا كَانَ اللَّهُ لِيُسَلِّطَكِ عَلَى ذَلِكَ " . أَوْ قَالَ " عَلَىَّ " . قَالَ فَقَالُوا أَلاَ نَقْتُلُهَا قَالَ " لاَ " . فَمَا زِلْتُ أَعْرِفُهَا فِي لَهَوَاتِ رَسُولِ اللَّهِ ﷺ .
