9. This Quran guides to what is most upright; and it gives good news to the believers who do good deeds, that they will have a great reward.
Allah has revealed the last book of His Divine teachings, the Holy Quran, to guide mankind to the happiness of both worlds, and to guide them to the right path until the Day of Judgment.
The Quran guides people of all time and place to happiness both in this world and in next world. It guides the right path in all areas of human life. The guidance of the Holy Quran is the most direct guidance in the field of belief, faith, spirituality, values and ideology.
The guidance of the Holy Quran is the guide to the right path to the moral, economic, social, family and political life of man in this world.
The guidance of the Holy Quran is the most direct guide to the happiness of the Hereafter.
10. And those who do not believe in the Hereafter—We have prepared for them a painful punishment.
Ignorance is the aberration from the right path. Those who have gone astray will never succeed. First and foremost, they will not achieve a goal in this world. That is because they have no faith, and there is no Quran that guides to the right path. And they will not be able to attain their goal in the Hereafter. This is also due to the lack of faith and the absence of the Quran to guide the right path. As a result, they strike themselves in different ways. The lusts of their souls fall into their own lusts. They are exposed to various situations without knowing what is good or bad for them.
