[Eujacwta]

I think in your long winded way - you are admitting that the answer is apparently no it does not say anywhere in these CLASSICAL book that Imam Abu Hanifah (raa) had not taken from Imam Ja'far al-Sadiq (raa).

now you go have your argument with....

Allamah Shibli Numani (ra)

the great Muslim historian
an important professor at Aligarh,
the principal of Nadwat tul-‘Ulum,
the founder of the Shibli National College
the founder of the Darul Mussanifin in Azamgarh
the master of several Muslim languages,
the mentor of the great Muslim thinker Syed Sulaiman Nadvi (ra)
the author of the first portion of the great Sirat-un-Nabi.

who had access to every classical source that you do and more,
who had access to the historical works and documents possessed by Aligarh
and several other majot Muslim institutions
before he made this conclusion and refuted the view of Ibn Taymiyyah (ra) on the subject

you can find his grave somewhere in south Asia I believe.

and you can go have your argument with...

Sheikh Muhammad Abu Zahra al Azhari (ra),

the great Muslim historian of Egypt
teacher at al-Azhar's faculty of theology,
a professor of Islamic law at Cairo University
and member of al-Azhar's Academy of Islamic Research.

who refuted Ibn Taymiyyah's view on this,
who had access to every classical source that you do and more,
including having access to the historical works and documents
possessed by Al Azhar University and Cairo University before he too came to the same conclusion.

you can find his grave somewhere in Egypt I believe.
