brother I was just giving one of the proofs that the non Shafi'is adduce for not reading Qunut regularly in Fajr prayers like the Shafi'i school does. If you read the evidence of the Shafi'is you will find that their opinion is also rooted in the opinions of a group of the Salaf and the difference has arisen from the understanding of certain ahadith particularly that of al Bara' ibn 'Azib. Secondly there are some traditions that state that the Prophet recited Qunut till he died. There is a difference of opinion regarding one narrator called Abu Ja'far Razi. Some scholars have disparaged him and some have praised him. This has resulted in acceptance of the hadith by the Shafi'i school and non acceptance by the Hanafis. It is a matter of ijtihad and a person who has not reached that level is likely to get confused. So, the simple thing for the non Mujtahid to do is follow his school. Rest assured, it has a firm basis in the Qur'an and Sunna.
No mas'ala is decided on the basis of a single hadith. I was just presenting one of the evidences of the Hanafi school. That does not mean that the Shaf'i school does not have its proofs. Put a sock in it.
