How can one respond to the insinuation raised concerning Imam al-Bukhari and his efforts in collecting hadith, which questions the possibility of his collecting a massive number of hadiths within a specific timeframe, especially given that he used to take time in verifying them?

This estimation does not align with the reality of Imam al-Bukhari's life for several reasons: 1. The sixteen years refer to the duration of compiling his book "Al-Sahih," not the period of his seeking and memorizing hadith. He was inspired to memorize hadith while still in elementary school, at the age of ten or less, and he memorized the books of Ibn al-Mubarak and Waki' at the age of sixteen. 2. Al-Bukhari was endowed with a strong memory and speed of memorization, which enabled him to gather a vast amount of knowledge. His contemporaries testified to this; he would look at a book once and memorize its contents. Some even preferred him over Imam Ahmad ibn Hanbal. 3. The figure of six hundred thousand hadiths includes many duplicated hadiths due to the multiplicity of their chains of transmission.

As for the non-preservation of the original manuscripts of his books in which he collected hadiths, this is because the knowledge of a scholar that endures is what his students transmit, or what he incorporates into his compiled works that scholars transmit across ages, such as "Al-Sahih," "Al-Adab Al-Mufrad," "Al-Tarikh," and others.
