We all believe that the shaitan is our enemy and he will do any thing to destroy us .But the question is why we all follow his path. Shaitan is the main cause of Adam depart from heaven. Shaitan is always with us try to move us from the right path. To understand the whole incident first of all we must read the Verse of Holy Quran mentioned below:
"But the Shaitan made them both fall from it, and caused them to depart it from what (state) in which they were; and We said: Get forth, some of you being the enemies of others, and their is for you in the earth an abode and a provision for a time."
(Para No:1 & Verse No: 36)
In this verse Allah told us that the Shaitan is responsible for the dissidence of Adam and they both eat that food which was prohibited for them. The question is why they did so, there are million reason to justify or unjustified them but the most important thing is that the shaitan is responsible for this misdeed as mentioned in the Holy Quran.
If this incident will not happened then we will never understand that shaitan is our enemy. The main thing is that he is not happy with the birth of Adam; but it is also true that most of the mankind worship of this shaitan from the centuries in many shapes. Until or unless we will not believe that shaitan is our actual enemy we will not walk on the right path. We have to fight with this enemy from our first sigh to last breath.
We know that he is our enemy but actually in all our life we make shaitan our best friend. We first know that all those who want that we do some sin or wrong deed is not our friend; he is in shape of shaitan. This is our last stand which we will take first.
