However, the sentence which says: “… verily He is Forgiving, Thankful …” shows that the first grace of Allah unto them is that very forgiveness of their sins and the faults they might have had, since the most anxiety of a person is the anxiety about this issue. After having peace of mind from this point of view, He involves them in His thankfulness, i.e., He thanks for their good deeds and endows on them the best reward.

Amir-ul-Mu’mineen Ali (a.s.) says: “Is there no free man who can leave this chewed morsel (of the world) to those who like it? Certainly, the only price for your selves is Paradise. Therefore, do not sell your selves except for it.” [^1] [^1] Nahj-ul-Bala-qah, saying No.
