1. لا تُحَمِّل أَخاكَ مالا يُطيقُ

    فَسِوى ذاكَ بِالإِخاءِ عُقوقُ

    Do not burden your brother with what he cannot bear;

    For doing otherwise is a betrayal of brotherhood.

  2. لَيسَ بِالصادِقِ الصَداقَةِ عِندي

    غَيرُ مِن لا يُجاحُ مِنهُ الصَديقُ

    In my view, no one is sincere in friendship

    Except one whose friend suffers no ruin at his hands.
