What is meant by belief in the Last Day?

Belief in the Last Day means firm conviction in everything that Allah and His Messenger (peace be upon him) have informed us about regarding what will occur after death. This includes the signs of the Hour, death, the trial of the grave, its torment and its bliss, the blowing of the Horn, the Resurrection, the terrors of the Day of Judgment, and the details of the gathering and the reckoning, Paradise and Hellfire.

The fruits of this belief are: desire for acts of obedience, dread of sins, and solace for the believer concerning what he misses of worldly pleasures.
