Then Allah tells us of His greatness, and that worship should be directed to Him alone, not to any of the idols which do not create but are rather themselves created. Thus He says

[أَفَمَن يَخْلُقُ كَمَن لاَّ يَخْلُقُ أَفَلا تَذَكَّرُونَ ]

(Is then He, Who creates, the same as one who does not create Will you not then reflect)(16:17). Then He shows His servants some of the many blessings He granted for them, and the many kinds of things that He has done for them. He says;

[وَإِن تَعُدُّواْ نِعْمَةَ اللَّهِ لاَ تُحْصُوهَآ إِنَّ اللَّهَ لَغَفُورٌ رَّحِيمٌ ]

(And if you would try to count the favors of Allah, you would never be able to count them. Truly, Allah is Forgiving, Most Merciful.) (16:18) meaning that He pardons and forgives them. If He were to ask you to thank Him for all of His blessings, you would not be able to do so, and if He were to command you to do so, you would be incapable of it. If He punishes you, He is never unjust in His punishment, but He is Forgiving and Most Merciful, He forgives much and rewards for little. Ibn Jarir said: "It means that Allah is Forgiving when you fail to thank Him properly, if you repent and turn to Him in obedience, and strive to do that which pleases Him. He is Merciful to you and does not punish you if you turn to Him and repent.''

[وَاللَّهُ يَعْلَمُ مَا تُسِرُّونَ وَمَا تُعْلِنُونَ - وَالَّذِينَ يَدْعُونَ مِن دُونِ اللَّهِ لاَ يَخْلُقُونَ شَيْئًا وَهُمْ يُخْلَقُونَ - أَمْوتٌ غَيْرُ أَحْيَآءٍ وَمَا يَشْعُرُونَ أَيَّانَ يُبْعَثُونَ ]

(19. And Allah knows what you conceal and what you reveal.) (20. Those whom they invoke besides Allah have not created anything, but are themselves created.) (21. (They are) dead, not alive; and they do not know when they will be resurrected.) Allah tells us that He knows what is hidden in people's hearts as well as what is apparent. He will reward or punish everyone for their deeds on the Day of Resurrection. If their deeds are good then they will be rewarded, and if their deeds are evil, then they will be punished.
