Shama-il Tirmidhi Chapter 25, Hadith Number 17 (159).

Ibn Mas’ud Radiyallahu ‘Anhu says: “Rasulullah Sallallahu ‘Alayhi Wasallam loved the meat of the forequarter. Rasulullah Sallallahu ‘Alayhi Wasallam was-given poison in the dhiraa portion of the meat. It is suspected that the Jews poisoned him’.

Commentary.
Aafter -Khaybar was conquered, a Jewess living there, came to know that Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam loved the dhiraa portion of the meat. She roasted the meat of a goat and mixed a poison in it, and especially put more in the dhiraa part. She invited Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam and served the meat. Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam took a bite but did not swallow it, or may have swallowed a bit of it then spat it out and said. ‘I have been informed by this meat that there is poison in it”, some of the poison affected him. The poisonous effect sometimes became severe, and at the time of his demise it began to take effect again and was the cause of his martyrdom. In this hadith it is mentioned that the meat itself informed Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam that there was poison in it. In other narrations it is stated that Jibra’eel ‘Alayhis Salaam informed him of this. There is no contradiction, is both are possible, first the meat must have informed him as a mu’jizah (miracle), thereafter Jibra’eel ‘Alayhis Salaam came and affirmed it After receiving the information, Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam stopped eating it and prohibited the Sahaabah Radiyallahu ‘Anhum from eating it too. Later the woman was called and asked if poison was mixed in the meat? She confessed that she had poisoned the meat. Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam did not avenge himself and the woman was pardoned at that time. But later Sayyidina Bishr bin Baraa Radiyallahu ‘Anhu was martyred due to eating the poisoned meat. We find in a few narrations that the woman was later killed as a punishment, or as an example to others. There are different narrations from which we gather that she was punished. In others that she was not punished. Both are correct, as is gathered from the original incident. According to the shari’ah for such a deed it is waajib to punish the murderer or blood money taken. This is a fiqhi question and the ‘ulama hold different opinions, which needs an academic discussion, therefore, it is omitted here. Sayyidina Ibn Mas’ud Radiyallahu ‘Anhu” saying that it is suspected that the Jewess poisoned the meat, is according to his thoughts, it seems he did not investigate this incident, otherwise the original incident has been ascertained. The Jewess also confessed her crime as is mentioned in other narrations.
