اُكْتُمْ ضَمِيرَكَ مِنْ عَدُوِّكَ جَاهِداً

وَحَذَارِ لا تُطْلِعْ عَلَيْهِ رَفِيقَا

Conceal your inner thoughts from your foe though with toil unceasing

And beware! Reveal them never to friend though he be pleasing

فَلَرُبَّمَا انْقَلَبَ الصَّدِيقُ مُعَادِياً

وَلَرُبَّمَا رَجَعَ الْعَدُوُّ صَدِيقَا

For ofttimes the trusted friend turns to be a bitter foe

And ofttimes the foe, once hated, proves a friend also
