"Knowledge is what comes from the Sahaba"

Al-Azwa'ee said:

العلم ما جاء به أصحاب محمد صلى الله عليه وسلم، فما كان غير ذلك فليس بعلم

ENGLISH:

"Knowledge is what comes from the [core rulings] of the Companions of Muhammad and that which does not come from a single one of them is not knowledge."

NEDERLANDS:

"Kennis is hetgeen dat afkomstig is van de metgezellen van Muhammad, vrede zij met hem. Dus al hetgeen niet van hen afkomstig is, valt niet onder 'ilm (kennis)."

["Jami' Bayān Al-'Ilm", ]
