25:32
وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَوْلَا نُزِّلَ عَلَيْهِ ٱلْقُرْءَانُ جُمْلَةً وَٰحِدَةً ۚ كَذَٰلِكَ لِنُثَبِّتَ بِهِۦ فُؤَادَكَ ۖ وَرَتَّلْنَـٰهُ تَرْتِيلًا

And the disbelievers say, “Why was the Qur’an not sent down to him all at once?” This is how We sent it in stages, in order to strengthen your heart with it and We read it slowly, in stages. - Ahmed Raza Khan (English)
