Which means: “Are there any who want to strive hard to receive the endowments of Paradise? Paradise has no equal. I swear by the Lord of the Ka^bah, it contains shining lights, pleasing fragrant plants, big castles, flowing rivers, ripe fruits, beautiful wives and many special clothes. [The residents of Paradise] will have beautiful faces. They will be immersed in endless bliss, living in high, sound, beautiful houses.” (Related by Ibn Hibban.) 

Hellfire: It is also called Jahannam. It is obligatory to believe that Hellfire is the everlasting place of torture. Allah prepared it for the blasphemers who chose blasphemy and refused Islam. The torture of Hellfire is real and physical. Its heat is much more unbearable than the heat of this world. Similarly, its coldness is far more severe than the coldness of this world. It is existent now. It is located beneath the seventh Earth. The blasphemers dwell in it forever and will not leave it.
