Ma'arif al-Qur'an Tefsir: Muhammad Aja 24

أَمْ عَلَىٰ قُلُوبٍ أَقْفَالُهَا (or do they have locks on their hearts? - 47:24) The meaning of this phrase is synonymous with similar phrases in other verses of the Qur'an where words like khatm or tab' "[ Allah ] has set a seal [ on their hearts ] have been used to describe how the disbelievers refuse to employ their hearts for the comprehension of truth, as a natural consequence their capacities to distinguish right from wrong have become atrophied. Carelessly, committing sins all the time is the main cause of this. Allah forbid!
