Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))

"... And they became like the dry stubble of a fold-builder. And indeed, We have made the Qur'an easy to understand and remember; then is there any that will remember (or receive admonition) ." (V.54:31,32)
(3)
Sahih al-Bukhari 4872

Narrated `Abdullah bin Masud:

The Prophet (ﷺ) used to recite: "Fahal-min-Maddakir (then is there any that will receive admonition?")

حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا أَبِي، عَنْ شُعْبَةَ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَرَأَ ‏{‏فَهَلْ مِنْ مُدَّكِرٍ‏}‏ الآيَةَ‏.‏
