The True Life

Islam teaches that this life is not the true life, because it is temporary.  This life is a test for people if they will search for the truth, believe in it, and do good.

Islam teaches that the true life is the afterlife, which is eternal.
But many people are busy working for this short life and its temporary pleasures, and do not prepare and work for the real eternal life after death.

Allah (God) said in the Quran:

{And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter – that is the [eternal] life, if only they knew.}
(The Quran 29:64)
