When Iblees noticed that the mould of Nabi Aadam (‘alaihis salaam) had a stomach, he realized that the human being would have desires due to which his condition will not be stable, and he will be able to influence man through his carnal desires.

(Saheeh Muslim #2611)

The Day when Nabi Aadam (‘alaihis salaam) was Created and Passed Away

Hazrat Aws bin Aws (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “Among the best of your days is the day of Friday. On Friday, Nabi Aadam (‘alaihis salaam) was created, on Friday, he passed away, on Friday, the trumpet will be blown, and on Friday, the creation will fall unconscious, so increase your Durood upon me on the day of Friday as your Durood is presented to me.”

The Sahaabah (radhiyallahu ‘anhum) enquired, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! How will our Durood be presented to you, whereas your body will decompose in the grave after your demise?”

Rasulullah (sallallahu ‘alaihi wasallam) replied, “Indeed, Allah Ta‘ala has prohibited the earth from consuming the bodies of the Ambiyaa (‘alaihimus salaam).” (Hence, my body will not decompose and I will be alive in my grave)
