﴿ وَأَقْبَلَ بَعْضُهُمْ عَلَىٰ بَعْضٍۢ يَتَسَآءَلُونَ ﴾

“And they [who are thus blest] will turn to one another, asking each other [about their past lives].”

And some among them will turn to one another questioning each other — they ask one another about how they were in the past and what they have now attained in their delight and acknowledgement of the grace of God to them.
