The human slope, and the exception that leads out of it
When the text says "the human being is…", it describes a slope: the human receives, deems himself self-sufficient, and falls. The way out is always an exception ("except", إلا), and that exception is made of deeds that acknowledge need: making contact, giving, enjoining one another to good, fearing one's Guardian.
The general statements are many, and they follow the same form. "The human being is certainly in loss, except those who have believed, done righteous deeds, and enjoined one another to truth, and enjoined one another to patience." (103:2-3). "We have certainly created the human being in the best of stature, then We reduced him to the lowest of the low, except those who have believed and done righteous deeds" (95:4-6). "the human being was created anxious: when evil touches him, he panics; and when good touches him, he withholds it — except those who make contact" (70:19-22).
The movement is always the same. The human receives a blessing; he sees himself self-sufficient (96:6-7, see “Seeing oneself self-sufficient, the reverse of purifying oneself”); he is "toward his Guardian, rebelliously ungrateful" (100:6). Then comes the exception, and it is made of deeds.
Sura 68 turns this into a story. The companions of the garden have received a harvest; they swear to gather it "without exception" (68:17-18); they set out "[deeming themselves] capable" (68:25); they find the garden ruined. The outcome is a confession: "We have indeed been wrongdoers." (68:29).
