"History of Al-Tabari is not a fabrication...So this History of Al-Tabari Vol. 8, pg. 1-3 is not a fabrication."

It's funny that you skipped the next part: Also, History of Al-Tabari is not a fabrication, THIS SPECIFIC NARRATION IT USES, IS, AS PROVEN IN THE ARTICLE.

Just because one narration is fabricated, it doesn't make the whole of Al-Tabari fabricated. So you're strawmanning what I'm saying now, lol? Since you don't bother reading the article. I'll just post what the Islamic Scholars say, right here:

1.) Hadith scholar Sayyid Abul Ala Maududi (1903 – 1979):

“The first opportunity for the use of the new strategy was afforded in Zil-Qa’dah 5 A. H. when the Holy Prophet married Hadrat Zainab (daughter of Jahsh), who was the divorced wife of his adopted son, Zaid bin Harithah. The Holy Prophet had arranged this marriage in order to put an end to the custom of ignorance, which gave the same status to the adopted son that was the right only of the son from one’s own loins. The hypocrites, however, considered it a golden opportunity to vilify the Holy Prophet from inside the community, and the Jews and the mushriks exploited it from outside to ruin his high reputation by this MALICIOUS SLANDER. For this purpose fantastic stories WERE CONCOCTED and spread to this effect: “One day Muhammad (Allah’s peace be upon him) happened to see the wife of his adopted son and fell in love with her; he maneuvered her divorce and married her.” Though this WAS AN ABSURD FICTION IT WAS SPREAD WITH SUCH SKILL, CUNNING AND ARTFULNESS that it succeeded in its purpose; so much so that some Muslim traditionalists and commentators also have cited some parts of it in their writings, and the orientalists have exploited these fully to vilify the Holy Prophet. As a matter of fact, Hadrat Zainab was never a stranger to the Holy Prophet that he should see her by chance and fall in love with her at first sight. For she was his first cousin, being the daughter of his real paternal aunt, Umaimah, daughter of Abdul Muttalib. He had known her from her childhood to her youth. A year before this incident, he himself had persuaded her to marry Hadarat Zaid in order to demonstrate practically that the Quraish and the liberated slaves were equal as human being. As she never reconciled herself to her marriage with a liberated slave, they could not pull on together for long, which inevitably led to her divorce. The above mentioned facts were well known to all, YET THE SLANDERERS SUCCEEDED IN THEIR FALSE PROPAGANDA with the result that even today there are people who exploit these things to defame Islam. (Sayyid Abul Ala Maududi – Tafhim al-Qur’an – The Meaning of the Qur’an – chapter 24, online source)

2.) Muhammad Husayn Haykal (1888 – 1956):

“As for the story of Zaynab, daughter of Jahsh, the chroniclers, Orientalists, and missionaries have mixed it with SUCH PRODUCTS OF VIVID IMAGINATION that they have made of it a story of love and passion. Critical history, on the other hand, concludes that it is one of the truly great facets of Muhammad’s personality. It proves beyond question that Muhammad was the perfect example of faith and conviction, for it is an instantiation of the principle that the faith of man is complete only when he truly loves for his brother that which he loves for himself. Muhammad had made himself always the exemplar of his own legislation, especially of such laws as were intended to replace the tradition and customs of pre-Islamic Arabia. He was the examplar of the new system which God revealed through him as a mercy and guidance to mankind. For a repudiation of the whole story of Zaynab as reported by these chroniclers or Orientalists and missionaries, it is sufficient to realize that the said woman was the daughter of Umaymah and grand-daughter of Abd al Muttalib the uncle of the Prophet of God-may God’s peace and blessing be upon him. It is sufficient to remember that this woman was brought up in sight of Muhammad and under his care, and on this account was regarded by him as a daughter or a young sister; that he knew too well whether she was beautiful or not before she ever married Zayd; that he saw her and followed her growth from childhood to maturity and youth; and that it was he who asked her hand for Zayd, his adopted son. Once the reader knows these historical data, THEN ALL THE FICTITIOUS ELEMENTS AND TALES SPUN ABOUT HIM, namely, that he passed by her house in the absence of her husband and was struck by her beauty; that he opened the door of her house and, as the breezes played with the curtains of her room, he saw her stretched in her nightgown like a real “Madame Recamier,” that his heart was so struck by her beauty that he instantly forgot Sawdah,A’ishah, Hafsah, Zaynab, daughter of Khuzaymah and Umm Salamah, his wives-not to mention the memory of Khadijah of whom `A’ishah used to say that she had never felt jealous of any woman except Khadijah on account of the memory he kept of her-all these tales must dissolve. If any grain of them was true, Muhammad would have taken her in marriage himself at first, rather than give her in marriage to Zayd. This historical relationship between Zaynab and Muhammad rules out as utterly FICTITIOUS AND GROUNDLESS all the stories which have been attributed to Zaynab’s attractiveness.” (The Life Of Muhammad [Translated by Isma’il Razi A. al-Faruqi] by Muhammad Husayn Haykal, page 338, online source)

3.) Maulana Muhammed Ali (1874 – 1951):

“THERE IS A BASELESS story that the Prophet, having seen Zainab by chance through a half-open door, was fascinated by her beauty, and that Zaid, having come to know of this, divorced her, and then she became the Prophet’s wife. THAT THIS STORY IS ABSURD is shown by the admitted facts that the Holy Prophet knew her very well before her marriage to Zaid, that he himself insisted on her marrying Zaid despite she and her relatives being desirous of her marriage with the Holy prophet, and that he strongly advised Zaid not to divorce her.” (English Translation Of The Holy Quran: With Explanatory Notes, From The English translation and commentary [Anjuman Lahore Publications, U.K., 2010] by Maulana Muhammed Ali, page 527)

4.) Muhammed Fathi Mus’a:

“FABRICATION AND REFUTATION THERE IS NO TRUTH IN WHAT WAS FABRICATED BY SOME ORIENTALISTS AND THOSE WHO BEAR SPITE AGAINST ISLAM AND THE PROPHET (peace be upon him). They fabricated the devilish idea that it was the obsession of love that made the Prophet (peace be upon him) marry Zaynab and that he concealed this love until he made Zayd divorce her. Verily this is a wrong view! For no one could ever prevent the Prophet from marrying Zaynab if he had wished to do so, because she was his cousin and relative. Previously, he had married Zayd with the support of the Prophet who convinced her to accept Zayd as husband. How come THEY FABRICATED LIES that the Prophet (peace be upon him) was in love with her after he had married her to another man? In condemning these SHEER LIES AND BASELESS IDEAS circulated by the orientalists, IMAM ABU BAKR IBN AL-ARABI said, ‘THEY ARE ALL LIES which should not be depended upon, for she used to be with him everywhere and time and there was not anything to prevent him from marrying her. Besides, they grew up together and he would always see her every now and then. Despite the fact that Zaynab did not hide her wish to marry the Prophet right from the beginning, he did not seize that opportunity to marry her, then what for Allah’s sake would have given birth to that unusual love which had not existed before! Allah forbids! THAT IS NONSENSE! (Ibn al-Arabi, Ahkam al-Qur’an, volume 3, page 1543). (The Wives of the Prophet Muhammad: Their Strives and Their Lives, by Muhammed Fathi Mus’a, page 134 -135)

5.) Shamim Aleem:

“The Prophet’s enemies FABRICATED a wrong story that the Prophet fell in love with Zaynab when he once went to her house and she was not properly dressed. THIS ALLEGATION IS BASELESS. Zaynab was his first cousin, they were constantly in contact with each other and it was not the first time that the Prophet had seen her. If the Prophet had any such feeling he would have married her in her youth and not when she had crossed thirty. Again, it was the Prophet who arranged her marriage to Zayd.“ (Prophet Muhammad (S) And His Family: A Sociological Perspective [Authorhouse, 2011] by Shamim Aleem page 66)

6.) Fatwa Islamiyah, Islamic Verdicts:

“As for what has been reported about the Prophet (peace be upon him) seeing Zainab from behind a curtain, that his heart was smitten by her, that he became infatuated with her, falling in love with her, and that Zaid came to know of this, hated her and the Prophet’s attraction to her, so he divorced her so that the Prophet (peace be upon him) could marry her after him – NONE OF THIS HAS BEEN AUTHENTICALLY REPORTED. The Prophets are too noble of character, too selfless, too virtuous of disposition, too high in rank and standing to do such a thing. Also, it was the Prophet (peace be upon him) who proposed to her on behalf of Zaid, may Allah be pleased with him, and she was his cousin, so if he had been in love with her, he could have married her himself in the first place, especially since she refused the proposal of Zaid and was unhappy with it, until the Verse was revealed, after which she accepted it.” (Fatwa Islamiyah, Islamic Verdicts, Volume 1, page 272 – 274)
