Allah shows His servants that they should worship Him Alone, for just as He is Independent in His power of creation and provision, so He should be worshipped Alone with no partners or associates such as idols and false gods. So Allah says:
(La ilaha illa Huwa. How then are you turning away (from Him)) meaning, `how can you turn away from Him after this has been made clear and this proof has been made obvious, but you still worship idols and false gods' And Allah knows best.
(4. And if they deny you, so were Messengers denied before you. And to Allah return all matters.) (5. O mankind! Verily, the promise of Allah is true. So, let not this present life deceive you, and let not the chief deceiver deceive you about Allah.) (6. Surely, Shaytan is an enemy to you, so take (treat) him as an enemy. He only invites his followers that they may become the dwellers of the blazing Fire.)
Allah says: `Even if these idolaters who associate others with Allah disbelieve in you, O Muhammad, and go against the Message of Tawhid that you have brought, you have an example in the Messengers who came before you.' They also brought a clear Message to their people and told them to worship Allah alone, but their people denied them and went against them.
(And to Allah return all matters (for decision).) means, `We will requite them for that in full.' Then Allah says:
(O mankind! Verily, the promise of Allah is true.) meaning the Resurrection will undoubtedly 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)
(7. Those who disbelieve, theirs will be a severe torment; and those who believe and do righteous good deeds, theirs will be forgiveness and a great reward.) (8. Is he, then, to whom the evil of his deeds is made fairseeming, so that he considers it as good Verily, Allah sends astray whom He wills, and guides whom He wills. So destroy not yourself in sorrow for them. Truly, Allah is the All-Knower of what they do!)
Having stated that the ultimate destiny of the followers of Iblis will be the blazing Fire, Allah then tells us that for those who disbelieve there will be a severe punishment. This is because they obeyed the Shaytan and disobeyed Ar-Rahman. And He tells us that those who believed in Allah and His Messengers
(and do righteous good deeds, theirs will be forgiveness) meaning, from whatever sins they did,
and a great reward for the good deeds that they did. Then Allah says:
(Is he, then, to whom the evil of his deeds is made fairseeming, so that he considers it as good) meaning, `such as disbelievers or immoral persons who do evil deeds and believe that they are doing something good, i.e., a person who is like that has been misguided by Allah, so what can you do for him You cannot help him at all.'
(Verily, Allah sends astray whom He wills and guides whom He wills.) means according to His decree.
(So destroy not yourself in sorrow for them.) means, do not grieve about that, for Allah is Wise in His decree and He leaves astray whomsoever He leaves astray, and He guides whomsoever He guides, and in doing so He has perfect knowledge and wisdom. Allah says:
(Truly, Allah is the All-Knower of what they do!)
(9. And it is Allah Who sends the winds, so that they raise up the clouds, and We drive them to a dead land, and revive therewith the earth after its death. As such (will be) the Resurrection!) (10. Whosoever desires Al-`Izzah then to Allah belongs Al-`Izzah. To Him ascend the good words, and the righteous deeds exalt it, but those who plot evils, theirs will be a severe torment. And the plotting of such will perish.) (11. And Allah did create you from dust, then from Nutfah, then He made you pairs. And no female conceives or gives birth but with His knowledge. And no aged man is granted a length of life nor is a part cut off from his life, but is in a Book. Surely, that is easy for Allah.)
