This life is a test, for a true believer , the Quran is the final Devine message for humanity, and it's so explicit:
* So for a believer, life is s competition to get a huge reward, so he prefers to be ready to be successful, wants to be wise, works to follow Devine commandments, he knows that this life is short so he does his best to be on the right path and deserve Paradise
* As for an unbeliever there's no test, our life is just fun and then nothing, we just go, no God, angels, prophets, devine, scriptures and no judgement... He just don't care about Devine warnings... although, for sure, the challenge is so high, and a severe punishment is awaiting those who took this life as only amusement, and didn't pay attention for the devine warnings, ...when death comes they will see the unexpected!
Quran
Chapter 59
20. Not equal are the inhabitants of the Fire and the inhabitants of Paradise. The inhabitants of Paradise—they are the victorious.
21. If We had revealed this Quran upon a mountain, you would’ve seen it humbled, shattered from fear of God. We present these parables to people, so they may reflect.
22. He is God, besides whom there is no god, the Knower of the invisible and the visible. He is the Gracious, the Merciful.
23. He is God, other than whom there is no deity, the Sovereign, the Sacred, the Source of Peace, the Giver of Faith, the Overseer, the Mighty, the Compeller, the Majestic. Glory be to God, far beyond what they associate with Him.
24. He is God, the Creator, the Inventor, the Designer. To Him belong the most beautiful names. All that’s in the heavens and the earth declares His glory. He is the Almighty, the All-Wise.
