الجَهلُ عُذرٌ وَلَيسَ العلمُ مَعذرةً

وَإِنَّ ذا الأَمرِ بَينَ النَّاسِ مَشهورُ

Ignorance is an excuse, but knowledge is no justification

This matter is well known among people

فَالعالم النَّدب لَم تَنفَعهُ مَعذِرةٌ

وَالجاهِلُ الغَمْرُ بَينَ النَّاسِ مَعذورُ

So the scholar's remorse is of no use to him

While the ignorant person is excused among the people
