25:32
وَقَالَ ٱلَّذِینَ كَفَرُوا۟ لَوۡلَا نُزِّلَ عَلَیۡهِ ٱلۡقُرۡءَانُ جُمۡلَةࣰ وَ ٰحِدَةࣰۚ كَذَ ٰلِكَ لِنُثَبِّتَ بِهِۦ فُؤَادَكَۖ وَرَتَّلۡنَـٰهُ تَرۡتِیلࣰا
And those who disbelieve say: Why is the Qur'an not revealed unto him all at once? (It is revealed) thus that We may strengthen thy heart therewith; and We have arranged it in right order.
— Mohammed Marmaduke William Pickthall
