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].

[وَإِذَا فَعَلُواْ فَـحِشَةً قَالُواْ وَجَدْنَا عَلَيْهَآ ءَابَاءَنَا وَاللَّهُ أَمَرَنَا بِهَا قُلْ إِنَّ اللَّهَ لاَ يَأْمُرُ بِالْفَحْشَآءِ أَتَقُولُونَ عَلَى اللَّهِ مَا لاَ تَعْلَمُونَ - قُلْ أَمَرَ رَبِّي بِالْقِسْطِ وَأَقِيمُواْ وُجُوهَكُمْ عِندَ كُلِّ مَسْجِدٍ وَادْعُوهُ مُخْلِصِينَ لَهُ الدِّينَ كَمَا بَدَأَكُمْ تَعُودُونَ - فَرِيقًا هَدَى وَفَرِيقًا حَقَّ عَلَيْهِمُ الضَّلَـلَةُ إِنَّهُمُ اتَّخَذُوا الشَّيَـطِينَ أَوْلِيَآءَ مِن دُونِ اللَّهِ وَيَحْسَبُونَ أَنَّهُم مُّهْتَدُونَ ]

(28. And when they commit a Fahishah, they say: "We found our fathers doing it, and Allah has commanded it for us.'' Say: "Nay, Allah never commands Fahishah. Do you say about Allah what you know not'') (29. Say: "My Lord has commanded justice and that you should face Him only, in every Masjid and invoke Him only, making your religion sincere to Him. As He brought you (into being) in the beginning, so shall you be brought into being again.'') (30. A group He has guided, and a group deserved to be in error; (because) surely, they took the Shayatin as supporters instead of Allah, and think that they are guided.)
