لا تَلحَ في قَصدِ مَن لا خَيرَ فيهِ إِذا

ما اِستَحسَنَ المَرءُ فيهِ غَيرَ ما حَسنِ

Do not pursue the purpose of one who has no good in him, if

The person saw in him other than what was good.

فَرُبَّما دَعَتِ الظَمآنَ غُلَّتُهُ

إِلى ضَرورَةِ شُربِ الآسنِ الأَجِنِ

So sometimes extreme thirst calls him,

To the necessity of drinking from impure waters.
