Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty created Adam (peace be upon him) in his form, his height was sixty cubits. When Allah Almighty created him, He said: Go and greet that group of angels sitting there and listen carefully to what they reply to you, for indeed these words will be the greeting for you and your offspring. (He went and) said: As-salamu Alaikum. They replied: As-salamu Alaika wa Rahmatullah. That is, they added the words "wa Rahmatullah." Whenever any person enters Paradise, he will enter in the form (and stature) of Adam (peace be upon him). But (from the birth of Adam in this world) until today, the stature has been decreasing.

Brief Explanation
Benefits: … The original stature of man is sixty cubits, and every inhabitant of Paradise will have this same height. Gradually, there has been a decrease in stature, to the extent that now people consider a height of six or seven feet to be very handsome, and those of very tall stature have come to be regarded as odd. In reality, human nature is influenced by the surrounding environment. In Islam, great importance has been given to the greeting of salam (peace), and its initiation began with Adam alayhis salam. The Noble Prophet sallallahu alayhi wa sallam has commanded that salam be made widespread.
Shaykh al-Albani rahimahullah says: This narration supports the view of those who consider the word "Adam" to be the antecedent of the pronoun "him." The meaning of this hadith is: Allah, the Exalted, created Adam alayhis salam in the form in which He intended him to be, that is, he did not have to pass through various stages during his creation like his progeny do, nor did he have to go through the stages in the wombs of being a drop (nutfah), then a clot (alaqah), then a morsel of flesh (mudghah), then bones (‘izam), then flesh (lahm), and then complete creation (khalq tamm). Rather, as soon as Allah, the Exalted, breathed the soul into him, He made him complete and perfect, balanced and proportionate, and correct and sound. Imam Ibn Hibban rahimahullah has discussed this hadith in detail and beneficially; you may refer to it. (Sahihah: 449)
