“One day Muhammad went out looking for Zaid (Mohammed’s adopted son). Now there was a covering of hair cloth over the doorway, but the wind had lifted the covering so that the doorway was uncovered. Zaynab was in her chamber, undressed, and admiration for her entered the heart of the Prophet ”. (The History of al-Tabari , vol. 8, p. 4)
Narrated by Yunis, narrated by Ibn Wahab, narrated by Ibn Zaid who said, "The prophet -pbuh- had married Zaid son of Haritha to his cousin Zainab daughter of Jahsh. One day the prophet -pbuh- went seeking Zaid in his house, whose door had a curtain made of hair. The wind blew the curtain and the prophet saw Zainab in her room unclothed and he admired her in his heart. When Zainab realized that the prophet desired her SHE BEGAN TO HATE ZAID . English translation of al-Tabari’s Arabic Commentary on Sura 33:37
Then conveniently came the revelation:It is not for any believer, man or woman, when God and His Messenger have decreed a matter, to have the choice in the affair. Whosoever disobeys Allah and His Messenger has gone astray into manifest error. When you said to him whom Allah had blessed and you had favoured, ‘Keep your wife to yourself, and fear Allah,’ and you were concealing within yourself what Allah should reveal, fearing other men; and Allah has better right for you to fear him. So when Zaid had accomplished what he would of her, then We gave her in marriage to you, so that there should not be any fault in the believers, touching the wives of their adopted sons, when they have accomplished what they would of them; and Allah’s commandment must be performed. There is no fault in the prophet, touching what Allah had ordained for him."
Theer were a lot of haters of Islam even in early days who concoted false stories, hence somethign called chain of transmission was established by historian to verify the authenticity.
In both history of tabari and tafsir tabari, no chain is mentioned of this tradition.
It apears that you WANT to beleive anything against Islam, thats our choice but dont try to shove it upon us.
