On one occasion, Imaam Bukhaari (rahimahullah) travelled to the city of Baghdad. On hearing of his arrival in the city, a few Muhadditheen gathered and decided that they would test the memory of Imaam Bukhaari (rahimahullah). They wished to test him to determine his proficiency and mastery in narrating Hadith.

Thus, they selected one hundred Ahaadith and mixed the Ahaadith with the chains of other Ahaadith. Thereafter, they agreed that ten people among themselves will narrate these hundred altered Ahaadith to Imaam Bukhaari (rahimahullah), with each person narrating ten Ahaadith. They decided that after narrating the Ahaadith, they would ask Imaam Bukhaari (rahimahullah) regarding their authenticity.
