جَنَى السَّفِيهُ جناياتٍ فَحَلَّ بِمَن

لم يَجنِها ما أحَلَّ الشيبُ باللِّممِ

The fool committed crimes, so their punishment befell those

Who did not commit them, just as old age makes the brave man weak.

ولِلجَهَالَةِ عَدوَى يَستَضِرُّ بها

ذو العَقلِ إن لم يُجَانِب مَوضِعَ التُّهَمِ

And ignorance spreads its harm to the wise

If he does not avoid the abode of suspicion.
