1. مَن كابَرَ البُرهانَ في بِحثِهِ

    فَذاكَ لا يُحسَبُ إِنساسا

    Whoever obstinately disputes the proof in his inquiry

    is not to be counted human.

  2. لِأَنَّهُ إِن فاتَهُ فَهمُهُ

    فَدَمٌ وَإِلّا كانَ شَيطانا

    For if understanding it eludes him,

    he is a dullard; otherwise, he is a devil.
