Imam al-Bukhari is included in the launch set because many modern allegations about Islam rest on the assumption that Muslim scholars passed reports along carelessly. His life points in the opposite direction. He became famous for disciplined travel, careful comparison of narrations, and extraordinary concern for reliability.
That matters here because a reader cannot fairly judge claims about Islam without understanding how Muslim intellectual history handled evidence. Biographies of major scholars show that preservation, classification, disagreement, and scrutiny were not side issues. They were central to the scholarly tradition.
