1. إن تُعْتِبَ الخِلَّ في ذَنبٍ جَزاك قِلىً

    أو تُعْفِهِ يَبْقَ طُوْلَ الدهرِ يؤذِيكا

    If you reproach a friend for a fault, he repays you with aversion;

    or if you excuse him, he keeps hurting you for all time.

  2. فإنْ تُطِقْ تَجمع الضِّدَّيْنِ في نَسَقٍ

    فَرُبَّما قَد تَرى خِلّاً يُواتِيكا

    So if you can bring the two opposites together in a single sequence,

    then perhaps you may find a friend who agrees with you.
