What is the easiest way to memorize the entire Holy Qur’an or parts of it, and does the worm consume the body of the Qur’an memorizer in the grave?

The earth consumes the bodies of all human beings except for the bone of the tailbone ( ajb al-dhanab ). Allah has forbidden the earth from consuming the bodies of the prophets only. This does not prevent Allah from preserving the bodies of some of His saints as an honor to them. What is most important for a Muslim is to strive in obedience to Allah so that he may enjoy comfort in his grave and attain the greatest bliss on the Day of Resurrection, because "these bodies are nothing, but the souls are with Allah Almighty."
