كتاب الجنة و النار و صفتهماBook of Paradise and Hell and Their Description
The people of Paradise will be in the form of Prophet Adam in beauty and stature
Hadith 975
وَبِهَذَا، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: ((مَنْ دَخَلَ الْجَنَّةَ فَهُوَ عَلَى صُورَةِ آدَمَ وَلَمْ يَزَلِ الْخَلْقُ يَنْقُصُ حَتَّى الْيَوْمَ)).
It is narrated with the same (previous) chain, the Messenger of Allah, peace and blessings be upon him, said: "Whoever enters Paradise will be in the form of Adam, peace be upon him. (After Adam, peace be upon him,) the stature of people has continued to decrease."
