Indeed, We have sent down this Qur’an-Reading-upon you stage by stage.
Qur’an means for repeated reading. The soul of all 313 Books reveled from the Lord of the universe to all 313 Messengers from first Messenger Nooh to last Messenger Muhammed is Adhikr-the Reminder. Since they were revealed to different countries in different languages and in different periods, their bodies which is the languages were different. After the deputation of Muhammed as the Messenger, the Book for entire mankind is Adhikr-the Splendid Book mentioned in the verses 41: 41-42. Adhikr is the Word and Guidance from the Creator Lord for the entire mankind including Jains, Budhas, Hindus, Jews, Christians, Atheists, etc. Just like the bounties such as air, water, light and soil are meant for the entire creatures, Adhikr and Messenger Muhammed are also meant for whole world as mentioned in the verses 7: 157-158; 21: 107 and 34: 28. Adhikr is the Ultimate form of the previous Scriptures which testifies and Safeguards all the previous 312 Books revealed from the Lord, and their upright explanation as explained in verse 5: 48. As told in verses 7: 158; 21: 107 and 34: 28 that Muhammed is the Messenger to the entire mankind from his deputation toll the Last day.
The verses of Lord’s Book are revealed stage by stage in order to brace up the heart of Messenger and thereby the believers as told in verse 25: 32. It is told in verses 15: 90-91; 38: 87 and 81: 27 that Just like warners were deputed to different groups of people who neglected Adhikr-the Book for repeated reading-before, Muhammed is deputed as warner to the entire mankind. It is told in verses 17: 105-107, this True reading-Adhikr-is revealed stage by stage for reading It upon the people stage by stage.
Since Adhikr-the Best Interpretation of Lord’s Book-is codified through the Three Time Knower mentioned in the verse 25: 59, the Fujjar-Kuffar-who do not testify It will be dragged in to the Hell prone on their face, such are in the worst place and the most strayed as told in verses 25: 33-34. They are the worst creatures among thousand communities of lord’s creatures as told in verse 8: 22. See explanation 36: 69-70.
