We have not been blind followers.
Every opportunity on this forum, youtube or individual discussion I get I mention the absurdities, obscenities and fairy tales of the hadith.
One response I get all the time elsewhere is that you have to know the time and place of the hadith in order to understand them as a simple reading leads to the absurd, obscene and made up nature, which, of course, cannot happen to the sayings of a Messenger of Allah!
One person was so engrossed in his hadith that he did not realise that Bukhari wrote them 250 years after the Messenger though he had read Bukhari wrote them 250 years after the Messenger. The time gap had not registered in his brain as well as the chinese whispers, hearsay of dead people narrating the hadith!
The billboard is a wake up call to those who follow Bukhari instead of Allah.
