Summary of the concepts of Ahl al-Sunnah: Contemplation (tadabbur) and mindful remembrance (tadhakkur) manifest the blessings of the Qur'an. In the preceding verse, the Qur'an was likewise described as being blessed, after which contemplation and mindful remembrance were mentioned using the particle of causation (lām al-ta'līl): "that they may contemplate" and "that they may be mindful." This indicates that contemplation and mindful remembrance are the means and cause for attaining the Qur'an's blessing; that is, the blessing of the Qur'an is attained through contemplating and reflecting upon it. This is because blessing (barakah) signifies increase and growth, which is realized through contemplation, as it unfolds the manifold meanings of the Qur'an and broadens its guidance. The verse also generally indicates that contemplating the Qur'an is among the most virtuous of deeds, and that it is of a higher rank than recitation devoid of contemplation.
