dontconvert2islam tries talking hadith, torture of Kinana?

In answer to the video "Islamic Fire Torture"

A little prior to the battle of Khaybar, The prophet allowed an expedition with the purpose of assassinating Sallam ibn al-Huqayq al-Nadri, also known as Abu rafi'. He is not the same person as Kinana ibn Al Rabi' as some misinformed critics have tried portraying. Ibn Khatir for example in his tafsir cites them both as actively participating in the battle of the confederates, with al Huqayq playing a prominent role in gathering and inciting the Meccans in their bid to inflict a crushing blow on the nascent Muslim community. Elsewhere, by al Bayhaqi, he is said to have financed the coalition and provided weapons. 

After the issue of Bani Qurayza was settled, the Khazraj tribe, a rival of Al-Aws, asked for the Prophet’s permission to kill al-Huqayq, aka Abu Rafi, in the same manner that the Aws were permitted to execute a criminal mastermind, Kaab bin Al-Ashraf. Permission was granted provided that no women or children would be harmed, an instruction that was respected despite Abu Rafi's wife almost foiling the attempt. This happened prior to the siege of Khaybar, where he was mercifully allowed to remain following the defeat of the Jewish-Meccan alliance, and from where he kept on actively inciting the Muslims' enemies. 

Wars were started and innocent people lost their lives because of such incitements. The prophet thought that such a move would dissuade the people of Khaybar from pursuing their belligerent attitude but it did not. 

After the battle of Khaybar, The history books report that one of the chiefs of the Bani Nadir named Kinana ibn Rabi, who had been given amnesty and relocated to Khaybar, was put to death under the prophet's orders, by Muhammad ibn Maslama in retaliation for the murder of his borther Mahmud. The rest of the story according to which, prior to his death, he was supposedly tortured for his refusal to indicate the location of his hidden treasure, was copied by both Tabari and Ibn Hisham from Ibn Ishaq who doesnt give any isnad with it. 

This report was most probably a Jewish invention as it is known that ibn Ishaq, in his effort at collecting every possible historical account regardless of authenticity (leaving the authentication process to be conducted by the subsequent generations), would borrow Jewish stories from the prophet's battles.

Further, the prophet forbade any kind of torture involving burning, and in his pattern of conduct in the authentic reports, no precedent exists for such a behavior although he could have done so on many occasions. War prisonners are to be well treated, clothed, sheltered and fed. When imam Malik was asked the Islamic ruling on torturing war prisonners to obtain military information he replied that he had never heard of such thing being done in Islam. The prophet was disinterested in pursuing wealth, whether in his battles or his reportedly austere lifestyle which his wives complained about even when the community had grown more prosperous. Neither was Kinana's family put to death, as is read in the report. It is related that Kinana's brother was alive under Umar's caliphate.
