Tasting Death and The Illusion of This World (3:185)

A Great Triumph

3:185 Every person tastes death, then you receive your recompense on the Day of Resurrection. Whoever misses Hell, barely, and makes it to Paradise, has attained a great triumph. The life of this world is no more than an illusion.

Since believers go straight to paradise when they exit this world what does it mean that every person tastes death?
