When He created him...
When He created him, He said to him, "Go and greet that group of angels, and listen to their reply, for it will be your greeting (salutation) and the greeting (salutations of your offspring." So, Adam said (to the angels), As-Salamu Alaikum (i.e. Peace be upon you). The angels said, "As-salamu Alaika wa Rahmatu-l-lahi" (i.e. Peace and Allah's Mercy be upon you).
Thus the angels added to Adam's salutation the expression, 'Wa Rahmatu-l-lahi,' Any person who will enter Paradise will resemble Adam (in appearance and figure). People have been decreasing in stature since Adam's creation. Then you said: Narrated Abu Huraira: The Prophet said, "Allah created Adam in His picture, sixty cubits (about 30 meters) in height. When He created him, He said (to him), The "His" article here means Adam, which means that Allah created Adam in his picture, i.e.
Adam was not a child then grew up like other people. This also means to refute darwinism: Adam was created in his known picture (60 cubits...) and did not derive from any other animal creature. In the Hadith, the word which is used as "his picture" is : Ala Soorateh We know that Allah knew his plan for the entire world from the beginning except that human beings are not aware of that. Such plan is "PLAN". It is not a picture of something.
When you say that you have a picture, it means that you DO exist. You exist, hence, you have a picture. So, picture is the attribute of an existing thing or human being. That is why a photograph is called a "picture". If you see the picture of an animal, you will say that such animal DOES exist, or it DID exist. When Allah wanted to created Adam, there was no Adam. There was no picture of Adam, since there was no Adam.
As the rsult of this reasoning, "His" in "His picture" refers to the God, and does not refer to Adam. On the other hand, a plan which is not implemented yet remains a plan and is never referred as picture. The hadith could have been spoken as: And Allah created Adam based on his plan, Or And Allah created Adam by his knowledge, Or And Allah created Adam by his power. You can never find a single hadith anywhere (Even a garbage Hadith) that is said: And Allah created the earth in its picture.
And Allah created a cow in its picture. There is no single verse in the so called Twisted bible or the book of traditions where God has created an ass in its picture. There is, however, some lines at the beginning of the old testement LIKE: And Yahowah created Adam by his picture.
