How is the quran the book of guidance?

We will understand how Qur'an is guidance if we understand the meaning of guidance. Guidance means to lead, to show way, to assist from errors, to reveal etc
These are essential characteristics of Qur'an. I t will lead you to what is right. It tells how to conduct your life like your marriage-who you should and should not marry, Your food-what you should and should not eat,Your death-how should and should not inherit you etc.
You will discover that if you do what Qur'an ask you to do or refrain from what it forbids you, life will be easy for you to leave in terms of health ,business transactions, family leaving,intercommunity relationship etc.
To confirm this, Allah said in Qur'an chapter 2 verse 2 that : This is the book,which indeed with no doubt, and a guide for those who fear Him.
May Allah open our heart to receive and accept the guidance of the holy Qur'an

Al-Quran is a quidance for those, who have taqwa, and the meaning of taqwa is loving God the most -so you will want Him to love you and you will make effort by obeying Him and doing extra voluntary worship as well, and you will be scared that He will be angry with you, so you will make yourself far from disobeying Him, and things that may lead to it. Then the Quran is your guide how to achieve it. And if you achieve it, you will attain Paradise, and be saved from Hell Fire. I`m not promising you will have a nice life. That`s just wordly affairs. But your life will be good and pure.
Number one thing that Thq Book of Allaah is guiding you to, is tawHeed, which is the true meaning and appliance of a monotheistic life. This is what all of The Prophets -peace be upon them- have ordered to, but other sources have been distorted, and new religions have been invented, and people have started to worship creation -in fact the very people who ordered them to worship Allaah Alone- beside Him! E.g. christians associate Jeesus Son of Mary as a god beside God, as a son of God, as a part of God etc. And this is why it`s forbidden to make images, or to wear amulets in Islam, like christians make icons and wear a cross in their neck. And they are loving Jesus with the love that is due only to God. Similar is the case with hindus and so on. And this is what the Prophet MuHammad -may Allaah elevate his mentioning and send him peace- warned us of by saying: "Don`t go into extremes concerning me, as the christians went into extremes concerning `Iisaa Ibn Maryam. Verily I am only a slave and a messenger. So say `Abdullaahi wa Rasuuluhu (a Slave of God, and His Messenger)."

And it is the greatest miracle of Gods Messenger to all of us until the end of the world, so no-one of us can summarize how it is a guidance, or even know how. Understand? Allaah guides by it in innumerous ways. Listen to it: Go to: www.all-quran.com
