الْقُرْآنُ حُجَّةٌ لَكَ أَوْ عَلَيْكَ
Translation: The Qur’an is evidence in your favour or against you.

حُجَّةٌproof or evidence
لَكَin your favour
أَوْor
عَلَيْكَagainst you
Brief grammar: الْقُرْآنُ is the subject and حُجَّةٌ the predicate. Both لَكَ and عَلَيْكَ contain the pronoun كَ (“you”); the differing prepositions yield “for you” and “against you.” أَوْ separates the two possible outcomes.
