Surah 41. Fussilat, Ayah 50

Being fully convinced of his own merit (as expressed in the words, "This is but my due"), he is confident that - in case there should really be a life after death - his own flattering view of himself will be confirmed by God.

I.e., the truth of resurrection and of God's judgment.

I.e., the realization of the spiritual blindness in which they spent their life will in if self be a source of their suffering in the hereafter: cf. 17:72 - "whoever is blind [of heart] in this [worldl will be blind in the life to come [as well]".

I.e., man is, as a rule, so blinded by his love of this world that he cannot imagine its ever coming to an end. Implied in this statement is a doubt as to whether there will really be an afterlife, and whether man will really be judged by God on resurrection.

When men entertain false ideas of values in life, there are two or three possible attitudes they may adopt in reaction to their experiences. In the first place, their desire may be inordinate for the good things of this life, and any little check brings them into a mood of despair. See last note. In the second place, if their desire is granted, they are puffed up, and think that everything is due to their own cleverness or merit, and they forget Allah. Not only that, but they go a step further, and begin to doubt a Hereafter at all! If by chance they have a faint glimmering of the Hereafter, which they cannot help recognising, they think themselves "favoured of Heaven", because of some small favours given to them in this life by way of trial. Thus they turn all things, good or evil, away from their real purpose, because they are devoted to falsehood.
