Assalam-O-Alaikum @aaliarubab How are you?

Your post is very interesting. In it you have also asked different types of questions which is not easy for me.

Now as you asked the question, what does Human mean? So let me tell you that we read about humans in biology. In biology human are also call Homo sapiens. A human has all the qualities, including emotions, thoughts, experiences and comparisons.

Allah Ta'ala says about humanity in the Qur'an. Which Mafhoom is :

That whoever saved the life of one person saved the life of the entire humanity and whoever killed one person killed the entire humanity.

Best Wishes 😍 Always be happy
