Greed caused Adam to eat from the forbidden tree...
"He (Allah) said: 'Verily you shall be of the respited ones." But the story of Satan did not conclude to that only happening. When he found that he was banished from the throne of Allah*,* he increased his rebellion and obstinacy. Instead of repentance, returning toward Allah*,* and confessing his fault, the only thing Iblis asked for from Allah was that he desired to be respited until the day when all will be raised up.
"He (Satan) said: 'Since You have let me wander off, I will certainly lay wait for (deceiving) them in Your Straight Path '." Satan did not want, of course, to have a long life and to be alive in order to compensate the past, but he expressed his aim of this long life that, the same as he was wandered off, he could lay wait on the Straight Path of Allah and deceive them all, so that, the same that he got astray, they might go astray, too.
"Then I will certainly come upon them from before them, and from behind them, and from their right and from their left; and You will not find most of them thankful." In order to confirm and to complete his statement, Satan added that, not only he will lay wait on their way, but also he will come upon them from the sides of four directions to deceive them.
