Quran repeatedly threatens the unbelievers

Q: threats (the unbelievers are fuel for hell Quran, 2.24)

A: I repeat, the Most Beneficent, the Most Merciful, is reaching out to us again and over again, inviting us to a wonderful reward, a life of peace on Earth, and an eternal life of happiness and well-being. At the same time, He is also warning us again and again of the consequences of flunking this temporal, open-book exam, as, even though His love for His creatures is great, He is also the Most Just, and Always FULFILLS HIS PROMISE, thus the continuous reminder of Hell.
