It is reported from Nawas bin Sam’an that he heard Allah’s Messenger ﷺ say, “On the Day of Judgement the Qur’ān and those who believe in it and act upon it will be brought before God and Surah Baqarah and Surah Al-e-Imran as representatives of the whole Qur’ān will intercede before God on behalf of their followers that they are deserving of Mercy and Forgiveness and may be dealt with mercifully.
(Muslim)
Recitation of the Qur’ān means not only to recite it correctly, with correct pronunciation, with an intention to earn the pleasure of God but also to follow its teachings in practical life. It includes an attempt to understand and think over its verses to seek guidance from the Book. Also, one must not acquire the knowledge of the Qur’ān to earn worldly benefits. A believer must fulfil all these preconditions of the recitation of the Qur’ān.
Allah’s Messenger ﷺ gives the believers glad tidings that on the Day of Judgement Surah Baqarah and Surah Al-e-Imran will represent the whole Book to intercede before God on behalf of believers, and recommend their cases as deserving of Divine Mercy and Forgiveness. At a time when all human beings will be presented before God for the accountability of their deeds on earth, and when everyone will stand in need of the Mercy of God, the intercession of the Qur’ān may earn the pleasure and thus Mercy and Forgiveness of God for those who spent their life on earth in accordance with the teachings of the Holy Book.
