I would like to know if we will ever be seeing Allah swt?
Whether on day of judgement or in jannah with our eyes? Has any of the prophet or Imam has seen Allah swt with their eyes?

We will not abe to see Allah with our naked eyes. It’s possible to see Him with our heart. Meaning to feel His presence and be overwhelmed by that.
There is no one who saw and will see Allah. Even our Imams didn’t see Allah. This is impossible simply because Allah is not a matter that has weight and occupies a space. He is not limited by time nor by space. He is everywhere
