﴿ لِيُبَيِّنَ لَهُمُ ٱلَّذِى يَخْتَلِفُونَ فِيهِ وَلِيَعْلَمَ ٱلَّذِينَ كَفَرُوٓا۟ أَنَّهُمْ كَانُوا۟ كَٰذِبِينَ ﴾

“[He will resurrect them] to the end that He might make clear unto them all whereon they [now] hold divergent views, and that they who are bent on denying the truth [of resurrection] might come to know that they were liars.”

That He may make clear to them li-yubayyina is semantically connected to an implied yab‘athuhum ‘He will resurrect them’ what they differ with believers in of matters of religion by punishing them and rewarding the believers and that the disbelievers may know that they were liars when they denied the Resurrection.
