Why are you making Islam more complicated. Read and Understand the Surah Kaif as much as you can and whenever you want, donot read fast inorder to read fastly (at that moment the Qur'an curses you) Read it before the Jummah prayer and understand it as much as long as you can. The Qur'an will not run away from you, but it will be you who will be at work or run away from it. Take your time understanding it. Donot make your life difficult, Read Quran with proper Understanding, Slowly...Slowly, anny time you are free.
The main Issue here is "Understanding". hazrat Umar (R.A), the second khalifa took 10 years to understand the Surah Al-Bakarah...and for others, more than 8 years. So take your time Understanding the Qur'an Slowly and Comfortably, Donot read fastly so that you can be off of it. At such time none of your deed will be accepted, because the Qur'an himself curses you. The word of Allaah Cursing, we muslims don't want that.
What kind of Question is that? "Must I read the entire Surah Al-kaif"? Allaah is not forcing you to read it with force, nor reading it is a pillar of Islam. But Instead Allaah made it as a hidaya for the believers and unbelievers. So that you may Understand it, and what Allaah is asking you too do, and what Allaah is saying, what Allaah will doo. Why Allaah built the universe, why Allaah created the colors of life, life after death, greenery, green trees, solar system, the universe, metal, coal, gold, diamond, water, food, animals, birds, sealife, messengers, prophets, and the Earth. All human Answers are present over their. You should not just read it in Arabic but also in English, so you may Understand "yourself" and the "Creation", The Akhirat, the Judgement and the Jannah. I am not saying to not to read the Quran in Arabic, but also so that you may know what Allaah is saying, What is the beauty of Allaah. We alone find all the Answers in the Qur'an, Spend your time Understand it. People have written books on it. Why people are called "Scholars" becasue they have read the Quran with Understanding, They know what Allaah is saying, thats why their spirituality level and imaan is Clear. All Because of Understanding the Qur'an.
