O mankind, indeed the promise of Allah is truth, so let not the worldly life delude you and be not deceived about Allah by the Deceiver.
Indeed, Satan is an enemy to you; so take him as an enemy. He only invites his party to be among the companions of the Blaze.
Chapter 35 Fāţir : Verses 5-6
Reminder of the Resurrection
(O mankind! Verily, the promise of Allah is true.) meaning the Resurrection will undoubtedy come to pass.
(So, let not this present life deceive you,) means, `this life is as nothing in compare to the great good that Allah has promised to His close friends and the followers of His Messengers, so do not let these transient attractions distract you from that which is lasting.’
(and let not the chief deceiver deceive you about Allah.) This refers to Shaytan, as stated by Ibn `Abbas, may Allah be pleased with him. Meaning, do not let the Shaytan tempt you and divert you away from following the Messengers of Allah and believing what they say, for he is the chief deceiver and arch-liar. This Ayah is like the Ayah that appears at the end of Surah Luqman:
(let not then this (worldly) present life deceive you, nor let the chief deceiver deceive you about Allah) (31:33). Then Allah tells us of the enmity of Iblis towards the sons of Adam:
(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.’
(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:
(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)
