Syed Muhammad Naquib Al-Attas said this quote
“ Manuscripts - at least for Muslims who understand the subject - are to be read as books whose contents are to be known and understood, for that is why they were written, and not to be regarded as enigmatic specimens for critical textual and philological exercises. To them what is in the manuscripts is more important than what is on them, and so they say: Al-'ilmu fi'l-sudur la fi'l-sutur. ”
