ذِكْرُ الْبَيَانِ بِأَنَّ إِنْشَاءَ اللَّهِ الْخَلْقَ الَّذِي وَصَفْنَا، إِنَّمَا يُنْشِئُهُمْ لِيُسْكِنَهُمْ مَوَاضِعَ مَنِ الْجَنَّةِ بَقِيَتْ فَضْلًا عَنْ أَوْلَادِ آدَمَ

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  

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  

"يَبْقَى مِنَ الْجَنَّةِ مَا شَاءَ اللَّهُ أَنْ يَبْقَى، ثُمَّ يُنْشِئُ اللَّهُ لَهَا خَلقًا مِمَّا يَشَاءُ".
