How miserable those who die and leave their sins after them - 4th IMAM (A.S.)

You are not living in a permanent abode; you are in a temporary house that you will leave soon. How does a man stay after the departure of his matches? Blessed be those who are fearful of this world. 

How miserable those who die and leave their sins after them are! Beware; you have been told. Take the initiative; you have been respited. You are dealing with Him Who is never ignorant. He who counts your deeds is never remiss. Supply yourself (with the necessary provisions); the long journey is approaching you. Correct your guilt; it has been inflicted by a cureless malady. Do not think that I wanted only to censure, reproach, and dishonor you. I only wanted Allah to revive the opinions that you have missed and give you back your religious affairs that you have lost. This is because I remembered Allah's saying: Keep on reminding them. This benefits the believers. (Holy Qur'an 51:55)
