Knowledge removes the blindness from the heart of its owner

والعلم يجلو العمى عن قلب صاحبه كما يجلي سواد الظلمة القمر 

و ليس ذو العلم بالتقوى كجاهلها و لا البصير كأعمى ما له بصر

Knowledge removes the blindness from the heart of its owner -- Like the moon removing the black darkness

And the one who has knowledge of piety isn't like the one who doesn't -- And the one who see isn't like the blind who doesn't have sight

من جامع بيان العلم و فضله
