25:32
وَقَالَ الَّذٖینَ كَفَرُوا لَوْلَا نُزِّلَ عَلَیْهِ الْقُرْاٰنُ جُمْلَةً وَاحِدَةًۚ كَذٰلِكَ لِنُثَبِّتَ بِهٖ فُؤَادَكَ وَرَتَّلْنَاهُ تَرْتٖیلًا
Waqala allatheena kafaroo lawla nuzzila AAalayhi alquranu jumlatan wahidatan kathalika linuthabbita bihi fuadaka warattalnahu tarteelan

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
