1. أَجِدِ الكَلامَ إذا نَطَقْتَ فإنَّما

    عَقْلُ الفَتى في لَفْظِهِ المسموعِ

    Perfect your speech when you speak, for it is only

    in his audible words that a young man's intellect is revealed—

  2. كالمرْء يَخْتَبِرُ الإناء بصَوتِهِ

    فَيَرى الصَّحيحَ به منَ المَصْدُوعِ

    as a man tests a vessel by its sound,

    and thereby distinguishes the sound one from the cracked.
