A man came to al-Rida (AS) and enquired: “Does Your Lord have the power to place the heavens and the Earth and whatever is between them inside an egg?” Hence, he (AS) replied, Of course he can! In fact, He has placed it in something even smaller than an egg. He has placed it all in your eye, while it is smaller than an egg. For when you open it, you see the Heavens and the Earth and whatever is in between them. IF he has willed, He would have blinded you from it all.
