Will the Hafiz of the Qur'an remember on the Day of Resurrection what he memorized of the Qur'an, even if he died having forgotten it, or not having reviewed it? And can the Hadith be clarified: "The rewards of my Ummah were presented to me, even the speck of dirt that a man removes from the mosque. And the sins of my Ummah were presented to me, and I did not see a sin greater than a Surah from the Qur'an or an Ayah that a man was given, then he forgot it"?

The noble verses: "But when there comes the greatest overwhelming calamity – The Day when man will remember what he strove for" (An-Nazi'at: 34-35), speak about man remembering his deeds, good and evil, on the Day of Resurrection, not about remembering what he had forgotten of the Qur'an.

The "companion of the Qur'an" who attains the virtue mentioned in the hadith: "Recite and ascend, and recite as you used to recite in the worldly life," is one who combines memorization of the Qur'an with acting upon it, not merely recitation or memorization without action. Reading from the Mushaf (physical copy) does not equate to memorization by heart in this virtue. Evidence indicates that the intended meaning of "reciter" during the time of the Prophet, peace be upon him, was the one who had memorized it. And the great reward is associated with memorization due to the effort and perseverance involved, and because it is a communal obligation (fard kifayah).

The prophetic hadith: "The rewards of my Ummah were presented to me, even the speck of dirt a man removes from the mosque. And the sins of my Ummah were presented to me, and I did not see a sin greater than a surah from the Qur'an or an ayah given to a man then he forgets it," has a weak chain of narration by agreement of the hadith scholars, so it cannot be used as evidence.
