Al-Bukhaari vs 400 muhadithoon

Haafiz Ibn Hajar narrated that Abu al-Azhar said:

ENGLISH:

“Once four hundred muhaddithin had gathered in the city of Samarqand to test Imam Bukhari. They did this by mixing up the transmissions of Syria with the transmissions of Iraq and the transmissions of Iraq with the transmissions of Syria. Similarly, they inserted the transmissions of the Haram (Mecca) into the ones of Yemen and vice versa.  They did this to Imam Bukhâri for seven days, but could not mislead him in text or transmission a single time".

NEDERLANDS:

"Er kwamen ongeveer 400 hadith kenners van Samarqand voor zeven dagen bijeen om Muhammad Ibn Isma'iel Al-Bukhaarie op de proef te stellen. Zij mengden de (hadith) ketens van Sham met de ketens van Iraq en de ketens van Yemen met de ketens van Haramain (om hem door de war te laten raken). Zelfs na al dit slaagden zij er niet in om hem een fout te laten maken! Niet in de ketens (isnad) en ook niet in de betekennis (mathn)!"
