1. Abu Hanifa predates Bukhari by about a century.
In any system of historical recording Abu Hanifa and the Kufan school would be given more weight in terms of accuracy than a much later source (Bukhari).
2. The salah according to the 4 Sunni schools of thought are all valid as their arkan (pillars) and fara'id are all the same, they only differ in furoo' (subsidiary issues) such as raising of the finger during tasshahud.
Groups like the "Salafees" (a.k.a "Wahabis) make this a big issue even though all Sunni variations of salah (namaz) are valid.
The Albanee way to pray is Nasirudeen Albanee's own personal ijtihad (opinion of a scholar derived through research and interpretation) and even other "Salafees" disagree with him on some issues e.g. Sheikh Muqbil.
However they both follow books of alleged ahadeeth written 2 centuries after the prophet 'alaihi salam.
Abu Hanifa was the main Imam in the Kufan school from Iraq who are said to be followers of the sahabi Abdullah bin Masud (radi'Allahu anhu). Abu Hanifa's "fatawa" are in fact not his personal legal opinions but the opinions of him and the 40 experts that sat with him in the main mosque in Kufa.
The majority of the Hanafi school and its rulings disagree with "Abu Hanifa's fatawa" (the Kufan school in reality) and are based on the fatawa of his two main students, Abu Yusuf and Muhammad As-Shaybanee.
The problem is the Salafee teachings and mentality is very confrontational and aggressive and preaches that only they are right and all others are deviants and in essence enemies of Islam.
They claim they are the "ta'ifatul mansoorah" (victorious group) or "firqah najiha" (saved sect) mentioned in some ahadeeth and the rest of the Muslims fall amongst the 72 "deviant" groups.
In parts of Africa there have been fistfights in mosques over the correct way to pray e.g. in the Ivory Coast the traditional Malikis leave their arms besides their bodies, whilst the Salafees go mad and say this is wrong and castigate them.
3.
Salafiyaa is a national security threat to Bangladesh.
Salafism often leads to violent groups e.g. Salafi-J***di e.g. "Al-Qaeda" and we can see the effects of extremism in Pakistan.
They are intolerant of other Muslims and cause division.
Some ordinary Salafis are good and decent people believing they follow a pure form of Islam free of innovations, that is fine as long as they stay humble and seek to convince people of their ways politely and through evidence but not through insults, and coercion.
I could say more but won't.
Hizbut Tahreer are another deviant group who are hated by Salafis and who hate Salafis too. They claim their founder Taqiuddeen Nabahani was a Mujtahid mutlaq (absolute jurist) so on the same legal level as the founders of the four madhahib (Abu Hanifa, Malik, Shafi' and Ahmad) and Nabahani even had his own "salah" (similar to the Shafi school but with some alterations).
Ahlul Hadith are similar to Salafis but differ as Ahlul Hadith think Salafis have an inclination for the Hanbali madhab (true) whilst Ahlul Hadith believe in following Bukhari's ahadeeth (2 centuries after the prophet 'alaihi salaam).
Salafis are the followers of Abdul Wahab, a Hanbali scholar from the Najd, Saudi Arabia who in turn was influenced by scholars such as Abu Hayat as Sindhi (a Sindhi scholar from modern day Pakistan) whose scholastic lineage is from other scholars such as Shah Waliullah and Ahmed Sirhindi.

Moander, this isn't a good forum to ask such questions as you have many bigots and Bangladesh-haters on this forum, who swear, insult and gang up on anyone who disagrees with them.
