1. شِفاءُ العَمى طولُ السُؤالِ وَإِنَّما

    تَمامُ العَمى طولُ السُكوتِ عَلى الجَهلِ

    The cure for blindness is persistent questioning; only

    prolonged silence in ignorance makes blindness complete.

  2. فَكُن سائِلاً عَمّا عَناكَ فَإِنَّما

    دُعيتَ أَخا عَقلٍ لَتَبعَثَ بِالعَقلِ

    So ask about what concerns you, for

    you were called a man of reason only to put reason to work.
