Offering advice to his son, Hadhrat Luqmaan (alayhis salaam) said:
“O my son! This world is a deep ocean in which numerous people have drowned. In this ocean of the world make Taqwa your ship; fill it with Imaan and let its sail be Tawakkul (Trust) on Allah. Then, perhaps you may be saved from the disasters of the world. Without this, salvation is not possible.”

Allah Ta’ala has made this world a trial and a temptation, and He has commanded us to purify ourselves here in preparation for meeting Him on the Day of Qiyaamah. The one whose ship of life is not strong and sturdy will be buffeted in the stormy waves of this deep ocean of the world. His ship will toss violently and rudderless in the stormy waters and the depth of the ocean will ultimately claim him.

We are required to purify ourselves with Istighfaar and A’maal-e-Saalihah. The only way of achieving purification after departing from this world contaminated with earthly pollution is the Fire of Jahannum. Thus, Rasulullah (sallallahu alayhi wasallam) said that the most intelligent person is the one who makes preparation for the sojourn after Maut.
