Sahih al-Bukhari 6227

Yahya ibn Jafar narrated to us: Abd al-Razzaq narrated to us, from Mamar, from Hammam, from Abu Hurayrah, from the Prophet, peace and blessings be upon him, who said: Allah created Adam in his form, sixty cubits tall. When He had created him, He said, ‘Go and greet that group of angels who are sitting, and listen to how they greet you, for it will be your greeting and the greeting of your descendants.’ He said, ‘Peace be upon you.’ They replied, ‘Peace be upon you, and the mercy of Allah.’ They added, ‘and the mercy of Allah.’ Everyone who enters Paradise will be in the form of Adam. Creation continued to diminish thereafter until now.
