There would be left some space in Paradise as Allah would like that to be left. Then Allah would create another creation as He would like. (Using translation from Muslim 2848d)
عَنِ النَّبِيِّ ﷺ يَدْخُلُ أَهْلُ الْجَنَّةِ الْجَنَّةَ فَيَبْقَى مِنْهَا مَا شَاءَ اللهُ أَنْ يَبْقَى ثُمَّ يُنْشِئُ اللهُ لَهَا خَلْقًا مِمَّا يَشَاءُ
There would be left some space in Paradise as Allah would like that to be left. Then Allah would create another creation as He would like.
عَنِ النَّبِيِّ ﷺ قَالَ يَبْقَى مِنَ الْجَنَّةِ مَا شَاءَ اللَّهُ أَنْ يَبْقَى ثُمَّ يُنْشِئُ اللَّهُ تَعَالَى لَهَا خَلْقًا مِمَّا يَشَاءُ
[Machine] The Messenger of Allah ﷺ said, "Allah keeps in Paradise whatever He wills to keep, and Allah creates for it (Paradise) whatever He wills."
قَالَ رَسُولُ اللهِ ﷺ يَبْقَى مِنَ الْجَنَّةِ مَا شَاءَ اللهُ أَنْ يَبْقَى فَيُنْشِئُ اللهُ لَهَا خَلْقًا مَا شَاءَ
[Machine] The Messenger of Allah ﷺ said, "The people of Paradise will enter Paradise and Allah will allow them to remain in it as long as He wills. Then Allah will create for them a creation until it fills it."
قَالَ رَسُولُ اللهِ ﷺ يَدْخُلُ أَهْلُ الْجَنَّةِ الْجَنَّةَ فَيَبْقَى مِنْهَا مَا شَاءَ اللهُ فَيُنْشِئُ اللهُ لَهَا يَعْنِي خَلْقًا حَتَّى يَمْلَأَهَا
There would be left some space in Paradise as Allah would like that to be left. Then Allah would create another creation as He would like. (Using translation from Muslim 2848d)
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «يَبْقَى مِنَ الْجَنَّةِ مَا شَاءَ اللَّهُ أَنْ يَبْقَى فَيُنْشِئُ اللَّهُ لَهَا خَلْقًا مَا يَشَاءُ»
"يَبْقَى مِنَ الْجَنَّةِ مَا شَاءَ اللَّهُ أَنْ يَبْقَى، ثُمَّ يُنْشِئُ اللَّهُ لَهَا خَلقًا مِمَّا يَشَاءُ".
