19وَلا تَكونوا كَالَّذينَ نَسُوا اللَّهَ فَأَنساهُم أَنفُسَهُم ۚ أُولٰئِكَ هُمُ الفاسِقونَAli UnalAnd do not be like those who are oblivious of God and so God has made them oblivious of their own selves.1 Those, they are the transgressors.This verse is telling those who are oblivious of God and the believers: you are oblivious and unaware of yourselves. You do not want to remember death, although you always consider others mortal. You hold back when confronting hardship and rendering service, but believe that you should be the first to be rewarded when it is time to collect the wages. You do not like obeying God in your lives and follow your lusts and caprices, and so are oblivious of the purpose for your worldly life. To purify yourselves of this, carry out your responsibilities, be prepared for death, and forget whatever reward you might obtain in the world. You should never forget why you are here in the world and what you should do, and for what end you are heading. You should know your true leader and follow him. Otherwise, (a Day will come and) it will be said: “We are oblivious of you today (so do not hope for forgiveness and favor), as you were oblivious of the encounter of this day of yours, and your (lasting) refuge will be the Fire, and you have no helpers (45: 34).
