I had determined to kill you. Thereupon he said: Allah will never give you the power to do it. He (the narrator) said that they (the Companion's of the Holy Prophet) said: Should we not kill her? Thereupon he said: No. He (Anas) said: I felt (the affects of this poison) on the uvula of Messenger of Allah.  

أَنَّ امْرَأَةً يَهُودِيَّةً أَتَتْ رَسُولَ اللَّهِ ﷺ بِشَاةٍ مَسْمُومَةٍ فَأَكَلَ مِنْهَا فَجِيءَ بِهَا إِلَى رَسُولِ اللَّهِ ﷺ فَسَأَلَهَا عَنْ ذَلِكَ فَقَالَتْ أَرَدْتُ لأَقْتُلَكَ قَالَ مَا كَانَ اللَّهُ لِيُسَلِّطَكِ عَلَى ذَاكِ قَالَ أَوْ قَالَ عَلَىَّ قَالَ قَالُوا أَلاَ نَقْتُلُهَا قَالَ لاَ قَالَ فَمَا زِلْتُ أَعْرِفُهَا فِي لَهَوَاتِ رَسُولِ اللَّهِ ﷺ  

Anas b. Malik reported that a Jewess brought poisoned meat and then served it to Messenger of Allah ﷺ  

أَنَّ يَهُودِيَّةً جَعَلَتْ سَمًّا فِي لَحْمٍ ثُمَّ أَتَتْ بِهِ رَسُولَ اللَّهِ ﷺ بِنَحْوِ حَدِيثِ خَالِدٍ
