﴿ 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.”
