The Believers will see their Lord in Paradise as Allah wills

Question:

In the Hadith of the Messenger, it is stated:
Verily, you will see your Lord on the Day of Resurrection, just as you see the moon on a night when it is full... you will have no difficulty in seeing it.

1. Is it true that Allah will be seen on the Day of Resurrection? And is the above-mentioned Hadith authentic? And will all of the people see Him, or only the believers?

2. Some of the narrations of Hadith say that Allah, the Most Glorified, Most High descends in the third part of the night to the lowest heaven; is this correct?

(1) This Hadith is confirmed to be authentic, and it is a proof that the believers will see their Lord in truth, as Allah wills. As for the disbelievers, they will not see Him, as Allah says:
"No! Surely, they (the evildoers) will be veiled from seeing their Lord that Day. And many Hadiths have been narrated which confirm that the believers will see their Lord in Paradise. In addition the Qur'an proves it, as in Allah's Words:
Some faces that Day shall be Nadhirah (shining and radiant), looking at their Lord.

And His Words:
On screened couches, looking (at their Lord).

In what way they will see Him we do not know, although it is true, for the abode of the Hereafter cannot be compared to the life of this world, nor can the unknown be compared to that which is known; what is incumbent upon us is to speak of what we know.

(2) Authentic Hadiths have been reported concerning the descent, such as the words of the Prophet:
"Our Lord descends to the lowest heaven when the last third of the night remains, and He says: "Is there anyone who supplicates (Me) so that I would answer him. Is there anyone who seeks forgiveness so that I will forgive him. Is there anyone who turns (to Me) in repentance so that I will turn to him in forgiveness.

But this descent is one of the matters of the unseen; we accept it, but we do not venture to explain how it is. We simply benefit from the bounty of the last part of the night and the virtue of praying, supplicating (Allah) and seeking forgiveness at that time, and the reply can be expected.
