The Holy Qur'an
Al-Baqara [The Cow]
Chapter 2 Al-Baqara 286 verses
21. O mankind! Worship your Lord (Allah), Who created you and those who were before you so that you may become Al-Muttaqoon.
2. This is the Book (the Quran), whereof there is no doubt, a guidance to those who are Al-Muttaqoon (the pious and righteous persons who fear Allah much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Allah much (perform all kinds of good deeds which He has ordained)).
164. Verily! In the creation of the heavens and the earth, and in the alternation of night and day, and the ships which sail through the sea with that which is of use to mankind, and the water (rain) which Allah sends down from the sky and makes the earth alive therewith after its death, and the moving (living) creatures of all kinds that He has scattered therein, and in the veering of winds and clouds which are held between the sky and the earth, are indeed Ayat (proofs, evidences, signs, etc.) for people of understanding.
Fussilat [Explained in detail]
Chapter 41 Fussilat 54 verses
53. We will show them Our Signs in the universe, and in their ownselves, until it becomes manifest to them that this (the Quran) is the truth. Is it not sufficient in regard to your Lord that He is a Witness over all things?
54. Verily! They are in doubt concerning the Meeting with their Lord? (i.e. Resurrection after their deaths, and their return to their Lord). Verily! He it is Who is surrounding all things!

Al-Araf [The heights]
Chapter 7 Al-Araf 206 verses
184. Do they not reflect? There is no madness in their companion (Muhammad SAW). He is but a plain warner.
185. Do they not look in the dominion of the heavens and the earth and all things that Allah has created, and that it may be that the end of their lives is near. In what message after this will they then believe?
You have to enter Islam.
