QS. Al-Furqan [25:32]
Criterion
وَقَالَالَّذِيْنَكَفَرُوْالَوْلَانُزِّلَعَلَيْهِالْقُرْاٰنُجُمْلَةًوَّاحِدَةًكَذٰلِكَلِنُثَبِّتَبِهٖفُؤَادَكَوَرَتَّلْنٰهُتَرْتِيْلًا٣٢
waqaala alladziina kafaruu lawlaa nuzzila 'alayhi alqur‑aanu jumlatan waahidatan kadzaalika linutsabbita bihi fu‑aadaka warattalnaahu tartiilaan
And those who disbelieve say, "Why was the Qur'an not revealed to him all at once?" Thus [it is] that We may strengthen thereby your heart. And We have spaced it distinctly. [32]
