An introduction to the holy Quran and it's unsolved mysteries

Quran (Kareem) is a holy book which is the message of Allah (God) revealed for the betterment of humanity. This is the message of the same Quran when the world or human beings were born but it continued to be revealed to each prophet from time to time. The Prophet faithfully conveyed the message of Allah to the human beings as per the orders of Allah but the human beings kept cutting thorns in the holy book according to their selfishness as a result the human beings could not get the original (messages of Allah). After that Allah also continued to tell his messages to the incoming prophets through the angel (Jibrail) even then the changes in the book of Allah (Tauret Jabur Injil and other Saheefs) continued. After that the last book Quran Sharif (which exists till the end) on the last prophet Mohammad had to be sent (descended) for the good of mankind. Because the responsibility of this holy book has been taken by Allah Taala (God) Himself. Books for familiarizing Quran (Kareem) are very few and not good in Hindi so by the grace of Allah Taala this book has been published. Took the initiative to write. By the way this work is very delicate so if any mistake is found in the book please inform as soon as possible. So that the shortcoming of the book can be removed. I have shown this book to respected Maulana Mustafa Madani Nadvi Apart from this..
