Tafsir of Fatir 35:6

إن الشيطان لكم عدو فاتخذوه عدوا

Surely, Shaytan is an enemy to you, so take (treat) him as an enemy. meaning, `he has declared his enmity towards you, so be even more hostile towards him, oppose him and do not believe the things with which he tries to tempt you.'

إنما يدعو حزبه ليكونوا من أصحاب السعير

He only invites his followers that they may become the dwellers of the blazing Fire. means, `he only wants to misguide you so that you will enter the blazing Fire with him.' This is a manifest enemy, and we ask Allah, the All-Powerful and Almighty to make us enemies of Shaytan and to make us followers of the Book of Allah and of the way of His Messengers. For He is able to do whatever He wills and He will respond to all supplication. This is like the Ayah:

وإذا قلنا للمليكة اسجدوا ﻻدم فسجدوا إﻻ إبليس كان من الجن ففسق عن أمر ربه أفتتخذونه وذريته أولياء من دونى وهم لكم عدو بيس للظلمين بدﻻ

And (remember) when We said to the angels: "Prostrate yourselves unto Adam.'' So they prostrated themselves except Iblis. He was one of the Jinn; he disobeyed the command of his Lord. 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)
