﴿ وَإِذَا رَأَيْتَ ثَمَّ رَأَيْتَ نَعِيمًۭا وَمُلْكًۭا كَبِيرًا ﴾

“and when thou seest [anything that is] there thou wilt see [only] bliss and a realm transcendent”

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.
