The Holy Prophet (SAW) has said:


"The number of levels (stages) in Heaven is the number of Ayaat in the Quran, so when a recitor of the Quran enters into Heaven it will be said to him:  'Go up one level for every ayah you can recite,'  thus there will no one in a higher level than the Haafiz-e-Quran (one who has memorized the entire Quran)."
