seeing allah ta'ala

Verification of a Hadith

Q: I’ve often come across the question:

"In Jannah, more valuable than being in Jannah is to see Allah Ta’ala directly. Allah Ta’ala comes personally to visit that lady who wears niqaab in this world”.

I would like to know that is the authenticity of this question? ‎

Seeing Allah Ta'ala

Q: According to the Prophet (sallallahu alaihi wasallam), the believers will see their Lord in the lifeafter as they can see the moon. Please can you clarify more on the word “grasp” (tudrikuhu) in the Quranic verse: { No vision can grasp Him, but His Grasp is over all vision. He is the Most Subtle and Courteous, Well Acquainted with all things.}[6:103].

Does it mean they cannot see Him entirely like for instance when looking at the blue sky we only see part of it? And what is the meaning of the Hadith in which it is described that we will see Allah as we can see the moon.
