that the Messenger of Allah (ﷺ) said: "When Allah created Adam" (and he mentioned) the Hadith (#3076).

that the Messenger of Allah (ﷺ) said: "Indeed Allah Most High created Adam from a handful that He took from all of the earth. So the children of Adam come in according with the earth, some of them come red, and white and black, and between that, and the thin, the thick, the filthy, and the clean."

that 'Umar bin Al-Khattab was asked about this Ayah: And when your Lord brought forth from the Children of Adam, from their loins, their seed and made them testify as to themselves: "Am I not your Lord?" They said: "Yes! We testify," lest you should say on the Day of Resurrection: 'Verily, we have been unaware of this (7:172).'" So 'Umar bin Al-Khattab said: "I heard the Messenger of Allah (ﷺ) being asked about it. So the Messenger of Allah (ﷺ) said: 'Indeed Allah created Adam, then He wiped his back with His Right Hand, and his offspring came out of him. So he said: "I created these for Paradise, and they will do the deeds of the people of Paradise." Then He wiped his back, and his offspring came out of him. So He said: "I created these for the Fire, and they will do the deeds of the people of the Fire." A man said: 'Then of what good is doing deeds O Messenger of Allah!' The Messenger of Allah (ﷺ) said: 'Verily, when Allah created a man for Paradise, He makes him perform the deeds of the people of Paradise, until he dies doing one of the deeds of the people of Paradise. So Allah will admit him into Paradise. And when He created a man for the Fire, He makes him perform the deeds of the people of the Fire until he dies doing the deeds of the people of the Fire. So Allah will enter him into the Fire.'"

Muslim ibn Yasar al-Juhani said: When Umar ibn al-Khattab was asked about the verse "When your Lord took their offspring from the backs of the children of Adam" - al-Qa'nabi recited the verse--he said: I heard the Messenger of Allah (ﷺ) say when he was questioned about it: Allah created Adam, then passed His right hand over his back, and brought forth from it his offspring, saying: I have these for Paradise and these will do the deeds of those who go to Paradise. He then passed His hand over his back and brought forth from it his offspring, saying: I have created these for Hell, and they will do the deeds of those who go to Hell. A man asked: What is the good of doing anything, Messenger of Allah? The Messenger of Allah (ﷺ) said: When Allah creates a servant for Paradise, He employs him in doing the deeds of those who will go to Paradise, so that his final action before death is one of the deeds of those who go to Paradise, for which He will bring him into Paradise. But when He creates a servant for Hell, He employs him in doing the deeds of those who will go to Hell, so that his final action before death is one of the deeds of those who go to Hell, for which He will bring him into Hell.

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."
