According to Mubashir24 website, Ayman al-Astal spent long hours every day to memorize the verses.
He would repeat the Surahs to memorize them every day after morning prayers until 9 o’clock and again after school in the afternoon.
Ayman is also a top student at school, his father Esmaeel al-Astal, who is a university professor, says.
Four of Esmaeel’s children are now memorizers of the Quran.
He says he always reads the Quran after his morning prayers to encourage his children to also read and learn the Holy Book.
The Quran has 30 Juzes (parts), 114 Surahs (chapters) and 6,236 verses, and so memorizing the entire Quran is an achievement that requires a lot of efforts and time.
