Why is the book "Burhan Al-Itqan" a treasure trove for anyone interested in memorizing the Holy Quran, regardless of their level or amount of memorization?
For many reasons, including:

1- The book, with this methodology, is unprecedented, as far as I know. It is the first book on this subject in this form.
2- Its comprehensiveness: There is not a single aspect of the Holy Quran, from beginning to end, in which questions are not raised.
3- Gradual progression: You will find the first level in each part to be very easy, while the seventh level is very difficult, and whoever passes it will attest to his very high mastery. From the first to the seventh, you will experience an enjoyable escalation in terms of difficulty. (Each part has ten tests, 3 non-cumulative, and 7 cumulative).
4- If you have a test or a competition, whether in an academy, an Al-Azhar high school, a Sharia college, or a local or international competition, this book, if used correctly, will guarantee that if you are not first, you are definitely among the first.
5- The variety of questions in it, meaning you will find narrative questions, which is normal, and similar questions, you will find questions based on words, and questions based on sentences, you will find questions: choose the correct answer from between the brackets, and you will find questions that I am sure you have never come across in your life, and this is according to the consensus of all the specialists who have seen the book.

I remember once finding a notebook online with questions about the Holy Quran, random questions from the entire Quran. I was so excited about it—because such questions weren't common, at least at the time—that I went and printed it out and kept it. Nevertheless, I considered it a treasure, and I still keep it to this day, even though, as I told you, the questions were random and some of them were repeated within the notebook itself.
If you compare this to the methodical book, prepared by specialists, graded and varied, you will know its value. Praise be to God who enabled us to create it and helped us to complete it.
