Now, we set forth the evidence of those scholars and traditionalists who have clearly held it to be utterance of Amir-ul-Momineen (AS) so that it’s historical importance should become known. Among these scholars, some are those before as-Sayed ar-Razi’s period, some are his contemporaries and some are those who came after him, but they all related it through their own chain of authority.
1) Ibn Abil-Hadid al-Mu’tazili writes that his master Abu’l-Khayr Musaddiq ibn Shabib al-Wasiti(d.605 A.H) stated that he heard this sermon from ash-Shaykh Abu Muhammed Abdullah ibn Ahmed al-Baghdadi ( d.567 A.H) known as Ibn al-Khashshab and when he reached where ibn-Abbas expressed sorrow for this sermon having remained incomplete, ibn al-Khashshab said to him that if he had heard the expression of sorrow from ibn-Abbas, he would have certainly asked him if there had remained with his cousin any further unsatisfied desire because excepting The Prophet(AS) he had already spared neither the predecessors nor followers and had uttered all that he wished to utter. Why should therefore be any sorrow that he could not say what he wished? Musaddiq says that ibn al-Khashshab was a man of jolly heart and decent taste. I inquired from him whether he also regarded the sermon to be a fabrication, when he replied; “By Allah SWT, I believe it to be Amir-ul-Momineen’s(AS) word as I believe you to be Musaddiq ibn Shabib .” I said that some people regarded it to be as-Sayed ar-Razi’s production, when he replied; “How can ar-Razi have such guts or such style of writing? I have seen as-Sayed ar-Razi’s writing and know his style of composition. Nowhere does his writing match with this one and I have already seen it in the books written two hundred years before the birth of as-Sayed ar-Razi and I have seen it in familiar writings about which I know by which scholars or men of letters they were compiled. At that time, not only ar-Razi but even his father Abu Ahmed an-Naqib has not been born.”
2) Thereafter, Ibn Abi’l-Hadid writes that he saw this sermon in the compilations of his master Abu’l Qasim al-Bakh(Abdullah ibn Ahmadi) i(d. 317 A.H). He was the imam of the Mu’tazilites in the reign of al-Muqtadir Billah whose period was far earlier than even the birth of as-Sayed ar-Razi.
3) He further writes that he saw this sermon in Abu Jafar (Muhammed ibn ‘Abd ar-Rahman),ibn Qibah’s book al-Insaf. He was the pupil of Abu’l Qasim al-Bakhi and a theologian of imamiyyah (Shi’ite) sect. (Ref: Sharh of Ibn Abi’l-Hadid , vol:1, pp:205-206)
4) Ibn Maytham al-Bahrani (d.679 A.H) writes in his commentary that he had seen one such copy of this sermon which bore writing of al-Muqtadir Billah’s minister , Abu’l Hasan Ali ibn Mohammed ibn al-Furat(d.312A.H) (Ref: Sharh al-balaghah, vol:1, pp:252-253)
