﴿ 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 explain unto them) to the people of Mecca (that wherein they differ) that which they oppose in the matter of Religion, (and that those who disbelieved) in Muhammad (pbuh) and in the Qur'an and the Day of Judgement (may know that they were liars) in this worldly life when they claimed that there is no Paradise, hell, resurrection or reckoning.
