Allah keeps all features of a human being in DNA. Even before a person is aware of himself, all his features such as eye color, height, bone structure are present in DNA. Allah created DNA in a form that it can constantly reproduce and sustain its existence. Cells multiply out of the will of a person and thus the continuity of information is ensured. Millions of details regarding the human body are copied and thus transmitted to DNA without any flaw. Were a human being attempted to fulfill this operation himself, it would be extremely difficult not to err in this extraordinary complicated system. Surely such an error would mean the death of the cell. It is very obvious that DNA’s existence and replication is one of the facts that prove Allah’s superior intelligence to us. The flawless Creation of Allah is related in the following verses:
 

It is He Who gives Life and Death; and when He decides upon an affair, He says to it, "Be", and it is. (Surah Ghafir, 68)

Verily my Lord understands best the mysteries of all that He planned to do, for verily He is full of knowledge and wisdom. (Surah Yusuf, 100)
