quran:76:20 –

And when you look there ˹in Paradise˺, you will see pleasure and great dominion.  

And when you look there, that is to say, when you begin to look about in Paradise, you will see (ra’ayta is the response to idhā, ‘when’) bliss, that is indescribable, and a great kingdom, vast, without limit.
القرآن:٧٦:٢٠ –

وَإِذَا رَأَيْتَ ثَمَّ رَأَيْتَ نَعِيمًا وَمُلْكًا كَبِيرًا  

{وإذا رأيت ثم} أي وجدت الرؤية منك في الجنة {رأيت} جواب إذا {نعيما} لا يوصف {وملكا كبيرا} واسعا لا غاية له.
