25:32

Al-Furqaan 25:32

وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ٱلْقُرْءَانُ جُمْلَةًۭ وَٰحِدَةًۭ ۚ كَذَٰلِكَ لِنُثَبِّتَ بِهِۦ فُؤَادَكَ ۖ وَرَتَّلْنَٰهُ تَرْتِيلًۭا

Wa qaalal lazeena kafaroo law laa nuzzila 'alaihil Quraanu jumlatanw waahidah; kazaalika linusabbita bihee fu'aadaka wa rattalnaahu tarteelaa

And those who disbelieve say: Why has not the Quran been revealed to him all at once? Thus, that We may strengthen your heart by it and We have arranged it well in arranging.
