Warning against the Lures of Shaytan
Allah warns the Children of Adam against Iblis and his followers, by explaining about his ancient enmity for the father of mankind, Adam peace be upon him. Iblis plotted to have Adam expelled from Paradise, which is the dwelling of comfort, to the dwelling of hardship and fatigue (this life) and caused him to have his private part uncovered, after it had been hidden from him. This, indeed, is indicative of deep hatred (from Shaytan towards Adam and mankind). Allah said in a similar Ayah,
أَفَتَتَّخِذُونَهُ وَذُرِّيَّتَهُ أَوْلِيَآءَ مِن دُونِى وَهُمْ لَكُمْ عَدُوٌّ بِئْسَ لِلظَّـلِمِينَ بَدَلاً
(Will you then take him (Iblis) and his offspring as protectors and helpers rather than Me, while they are enemies to you What an evil is the exchange for the wrongdoers.) 18:50.
