In the Name of Allah, Most Gracious, Most Merciful
Imam Ghazali (ra) says, "The world is going to perish very soon. It will not endure; it makes false promises and never fulfils them; it seems to be at rest but, in reality, it is fleeting, though its motion is not perceptible to the senses.
People become conscious of its fleeting motion when it forsakes them altogether. It is like a shadow that is in motion all the time, but its movement is not perceptible".
Once, when there was a mention of the world before Hasan Basri (ra), he stated:
"It is like a dream that the people have, in sleep; or like a shadow always in motion. The wise cannot be deceived by things like this".
Yunus ibn Ubaid (ra) says that he has suggested to himself the following similitude about the world:
"A man is asleep and dreams many things, good or bad. Suddenly, he wakes up and the dream is shattered.
Similarly, all men in the world are asleep; and all that they see or do is a dream. When they die, they wake up from the slumber, and there is no substance in the worldly joys or sorrows.
