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