The family of Prophet (S) all was following Deen-a-Ibrahimi.
It is a big lie that Hazrat Abu Talib was not a believer.
So-called fake Imam Bukhari was the staunch enemy of Islam Deen of Quran and Prophet (S). Do not trust his books. He wrote his books 250 years later of Propet (S) death.
He has written that his books are based on hearsay that is another lie. In fact, he invented the false stories and false Hadees and succeeded in brainwashing the entire Muslim world. The Muslims for over a thousand years are following his fake books instead of Quran.
