Hadith 19

(The book) ‘Uyoon Akhbar Al-Reza-asws’ – Al-Husayn Bin Muhammad Al Bayhaqi, from Muhammad Bin Yahya Al Sowly, from Awn Bin Muhammad, from Sahl Bin Al Qasim Al Nowshajany who said, ‘Al-Reza-asws said to me at Khurasan: ‘There is a lineage between us-asws and you all’. I said, ‘And what is it, O you emir? ’
He-asws said: ‘When Abdullah Bin Aamir Bin Kareyz conquered Khurasan, he attained two daughters of Yazdjard Bin Shahriyar, king of Persians. He sent them to Usman Bin Affan. He gifted one of them to Al-Hassan-asws and the other to Al-Husayn-asws. They-as both died with them-as of childbirth. The spouse of Al-Husayn-asws died Ali-asws Bin Al-Husayn-asws was blessed, so one of the mothers of the children of his-asws father-asws took responsibility, and he-asws grew up and he-asws did not know of any mother other than her. Then he-asws knew about her she was his-asws slave, and the people were naming her as his-asws mother, and they claimed that he-asws had married his-asws own mother, and Allah-azwj Forbid! But rather, this was married upon what we have mentioned, and the reason of that was that he-asws slept with one of his-asws wives, then went out to wash, and his-asws mother met him-asws, this. He-asws said to her: ‘If there was anything within yourself regarding this matter, then fear Allah-azwj and let me-asws known’ She said, ‘Yes’. So he-asws married her. The people said, ‘Ali-asws Bin Al-Husayn-asws married his-asws own mother! ’
Awn said, ‘Sahl Bin Al Qasim said to me, ‘There does not remain any student with us except he has written this Hadeeth from me, from Al-Reza-asws’’. [23]. (Propaganda of filthy minds against Ahl Al-Bayt-asws)
