Allah has informed us about His enemy, Iblis (the Satan), when He asked him why he refused to prostrate to Adam Iblis argued that he was better than Adam, and asked Allah to allow him respite, and He 98 allowed him so. Then Iblis, the enemy of Allah, said: {Because you have sent me astray, surely, I will lie in wait against them (on) Your Straight Path. Then I will come to them from before them and behind them, from their right and from their left, and you will not find most of them thankful ones).
The majority of the Interpreters of the Qur'an have explained that Satan's answer was in an ordered manner to show his determination to conspire against the believers.
Man follows one of four ways, and none else; he either takes a path on his right, left, in front of him or behind him. On each path, he finds satin lying in wait for him. If man follows any of these paths, while observing the Commands of Allah, he finds Satan laying obstacles against him to stop him from being obedient to Allah U. But if man follows any of those paths to commit sins, Satan will encourage him and provide all the support he needs.
