al-salamu `alaykum

As a small addition to the previous message:

Something that Imam Abu `Isa al-Tirmidhi did in his hadith
compendium that sets it apart from the other major works is that he
often mentions opinions from the Imams of the Salaf associated with
the various narrations.

Imam Abu `Isa titled the 232nd chapter of the compendium "What has
come concerning reciting behind the imam." He mentions that reciting
behind the imam is the practice of the majority of the scholars of
the Companions (Allah be pleased with them) and the Successors
(Allah grant them mercy), and it is the opinion of Malik bin Anas,
Ibn al-Mubarak, al-Safi`i, Ahmad, Ishaq: they were of the opinion of
reading behind the imam.

The next chapter is titled "What has come concerning not reading
behind the imam, when the imam recites audibly." Imam Abu `Isa
repeats much of what preceded,  but clarifies a few points. He said
that the majority of the Companions (Allah be pleased with them) and
the Successors and those who succeeded them (Allah grant them mercy)
were of the opinion that that one recites the Quran; this was the
opinion of: Malik bin Anas, `Abdallah bin al-Mubarak, al-Shafi`i,
Ahmad, and Ishaq. It seems that only the people of Kufa differed
from this opinion.

Some of  the proponents of reading behind the imam were so adamant
that they said that one must recite al-Fatiha, even when praying
behind an imam, and if he does not do so his prayer does not
suffice. al-Shafi`i and Ishaq were among those who went with this

Note that Imam Abu `Isa al-Tirmidhi did not mention here that Imam
al-Shafi`i had two opinions. He mentioned only one. Imam al-Tirmidhi
studied from students of Imam al-Shafi`i, and it seems unlikely that
he would mention a position other than the one Imam al-Shaifi`i's
students went by.

Now I wonder, did the author of that Hanafi work also mention that
some Hanafis consider followers reading behind the imam to be
recommended, and yet others consider it obligatory?
