Meaning of ignorance in Arabic
- ignorance; lack of knowledge The direct opposite of عِلْم (ʿilm, 'knowledge'). Classed as either simple (no knowledge of a thing) or compound (a false belief held as certain).
- foolish, silly, or wrongful conduct Extended from the verb جَهِلَ used of acting rashly, foolishly, or wrongly toward someone, not just of lacking information.
Example sentence
فَأقر لَهُ بِالْجَهْلِ فِي علمه، والآفات فِي عمله، والعيوب فِي نَفسه، والتفريط فِي حَقه، وَالظُّلم فِي مُعَامَلَته
So he acknowledges his ignorance in his knowledge, the flaws in his actions, the defects in his self, his negligence in his duty, and the injustice in his dealings.
بِالْجَهْلِ with the ignorance
bi- = 'with' (marks what is admitted); al- = 'the'; jahl means 'ignorance' — 'acknowledged… his ignorance'.

How it is used
جَهْل is the standard opposite of عِلْم ('knowledge'): it covers both a plain lack of knowledge and a false belief held with confidence. Classical usage widens it to foolish, reckless, or wrongful behavior, as in جَهِلَ عَلَى غَيْرِهِ, 'he acted foolishly/wrongly toward another.' Its adjective feeds الجَاهِلِيَّةُ, the term for the pre-Islamic 'Age of Ignorance.'
