Sahih Bukhari : Volume 1, Book 11, Number 579:
Bilal was ordered to repeat the wording of the Adhan for prayers twice, and to pronounce the wording of the Iqamas once except "Qad-qamat-is-Salat".
Sahih Bukhari : Volume 1, Book 12, Number 705:
Narrated 'Abdullah bin 'Umar:
I saw Allah's Apostle opening the prayer with the Takbir and raising his hands to the level of his shoulders at the time of saying the Takbir, and on saying the Takbir for bowing he did the same; and when he said, "Sami a-l-lahu Liman hamida ", he did the same and then said, "Rabbana wa laka-l-hamd." But he did not do the same on prostrating and on lifting the head from it."
Sahih Bukhari : Volume 1, Book 12, Number 706:
Whenever Ibn 'Umar started the prayer with Takbir, he used to raise his hands: whenever he bowed, he used to raise his hands (before bowing) and also used to raise his hands on saying, "Sami a-l-lahu Liman hamida", and he used to do the same on rising from the second Rak'a (for the 3rd Rak'a). Ibn 'Umar said: "The Prophet used to do the same."
My question is whether the above Hadith are true/trust-able? if the above hadith are correct then what why we do not follow? Again if the hadith is correct and few people follow, then why all/ most of the people dont follow as we have reference from a book that is valuable just after Al Quran.
If the Hadith is not correct or meant something else then why it is called Sahih Bukhari?
Please answer my question.
