Qalbu Al-Quran (Heart of the Koran) has many benefits, as the Prophet Muhammad SAW said, in the Al-Qur'an there are 30 Juz, 114 Surahs and 6666 verses. And each letter has its own heart/privacy. Whoever memorizes the heart of each letter, the reward is the same as completing the Al-Qur'an 1000 times, and the reward is like performing the pilgrimage, umrah and like giving gold as big as Mount Uhud. And whoever writes or keeps it unlawful for his body to hell. And his sins are forgiven, or more importantly the person who carries or uses it as an amulet, then he is guarded by the angels of hafadhah.
