أَفَلَمْ يَدَّبَّرُوا الْقَوْلَ أَمْ جَاءَهُمْ مَا لَمْ يَأْتِ آبَاءَهُمُ الْأَوَّلِينَ
68. Then have they not reflected over the Qur'an, or has there come to them that which had not come to their forefathers?
أَفَلَا يَتَدَبَّرُونَ الْقُرْآنَ أَمْ عَلَىٰ قُلُوبٍ أَقْفَالُهَا
24. Then do they not reflect upon the Qur'an, or are there locks upon [their] hearts?
أَوْ زِدْ عَلَيْهِ وَرَتِّلِ الْقُرْآنَ تَرْتِيلًا
4. Or add to it, and recite the Qur'an with measured recitation.
