The Prophet (ﷺ) said, "Allah created Adam in His picture, sixty cubits (about 30 meters) in height. When
He created him, He said (to him), "Go and greet that group of angels sitting there, and listen what they
will say in reply to you, for that will be your greeting and the greeting of your offspring." Adam (went
and) said, 'As-Salamu alaikum (Peace be upon you).' They replied, 'AsSalamu-'Alaika wa
Rahmatullah (Peace and Allah's Mercy be on you) So they increased 'Wa Rahmatullah' The Prophet (ﷺ)
added 'So whoever will enter Paradise, will be of the shape and picture of Adam Since then the
creation of Adam's (offspring) (i.e. stature of human beings is being diminished continuously) to the
present time." - Hadith Al Bukhari 6227 (islam)
