I found the book very good; it, along with the excellent book on Imam Abu Hanifa by Shaykh Nadwi, convinced me of the superiority of certain aspects of the Hanafi school which are not very well elucidated by other contemporary authorities. However, that is not the purpose of this thread. What I found interesting were two parts in particular-
Then on page 104 the Shaykh attributes the view of reciting al-Fatiha behind the Imam in silent prayers to one narration from Imam Abu Hanifa and one narration from Imam Muhammad, and then another group of noteworthy 'ulema, many of whom appear to have specialized in hadeeth.
On page 181, Shaykh Riyadh ul-Haq quotes a few ahadeeth and says that the Hanafi 'ulema believe it to be Sunnah to raise the finger at the time of negation and affirmation, then attributes the position of keeping it raised and steady until the end of the prayer (like in the Hanbali and Shafi'i schools) to Maulana Rashid Ahmed Gangohi and 'some other 'ulema.'
My question is, are these considered valid differences in the Hanafi school or are they considered shadh opinions?
