The Holy Quran
Like the holy Bible, Torah, Moses scriptues. Quran is the last Holy book, Devine from God, sent to His las Messenger Muhammad peace and blessings be upon him. As well as, the holy Quran is gathering everything told to all prophets and messengers before, such as Jesus, Moses, Abraham, Isaac, David, Jhon, Joseph...
The holy Quran is from the same God, the only and one God (Allah) who has no partner, no father, no mother, and no son. He is the creator of the whole universe who created us so as to worship Him and not to worship anyone or any thing beside Him. This truth is innate in us. He the almighty gave us a heart and brain which can guide us to believe in Him and stop being arrogants and selfish.
The Holy Quran comes to set the peace in all over the world, but people who do not know it, who never read it or understood it are always talking nonsense about it. The truth of the holy Qran is inside it, you only can reach this ruth when you read it carefully and look for the correct meaning of the words and the verse. While reading it let it lead you to the meaning and do not try to make the meaning of the verse as you like or as you wantit to be.
Islam
Unlike other religions, Islam is named in the holy book of God bay word. It is the name choosen by God to His worshippers and believers. The meaning of the word is very simple and easy to understand if you know Arabic language. It means to submitt onself to Allah (the one God) by worshipping Him only and not associating any partner with Him.
Also, through this subbmition to Allah you come to know and understad what does peace means and you live to spread peace all ovr the world, starting from yourself, your family and country. Jihad, Hijab, Booty, and beliefs are very big issues that comes through Shari'a (which is in general means Islam). So, every single word of these will take so many days or months of research and discssions if the person wants to understand it. And everything is coming from the holy Quran.
Mhammad peace and blessings be upon him
He is the las messenger of Allah (God), he cones right after the prophet and messenger of Allah Jesus peae and blessings be upon them both. He is a normal human being who was Illiterate, never has read or right, he was a simple trader who has no knowledge about religion or what related to it, which explains that he is a true messenger of Allah, because what comes in the Quran can not be imagination of any illiterate person, it is all a knowlede that takes ages to learn, and also a set of miracles no one knows about, and scientific knowledge that still scientists are discovering nowadays.
Once you know who is Muhammad you will never stop crying knowing how tough was his life not for any benefits but just because he wants thebest for us and likes to see everybody happy and living in peace whether they are believers or not.
