Hadīth explanation: The believer who is promised Paradise (in the Qur'an and Sunnah), if he had true knowledge of the punishment and torture that Allah has prepared for the people of disbelief and falsehood, he would not have any hope of entering Paradise; rather, his only hope would be to be saved from Hellfire, given what it contains of severe torture that human bodies would cannot bear. Contrary to that, if the disbeliever had true knowledge of the mercy of Allah, the Most Merciful and Most Generous, he would not despair of Allah's mercy; rather he would hope to enter Paradise because of what he knows about Allah's vast and extensive mercy and forgiveness.
