Allah tells:

وَاللّهُ يَعْلَمُ مَا تُسِرُّونَ وَمَا تُعْلِنُونَ
 
 

And Allah knows what you conceal and what you reveal. 

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.
<b>The gods of the Idolators are Created, they do not create</b> 

Then Allah tells:

وَالَّذِينَ يَدْعُونَ مِن دُونِ اللّهِ لَا يَخْلُقُونَ شَيْيًا وَهُمْ يُخْلَقُونَ
