Adam is created in order to consciously and willingly worships God, not because God needs worship, but because this gives Adam his unique identity. Adam was the highest of all creatures. He possessed the knowledge of all things in creation (and hence the ability to name them, which the angels lacked). In recognition of this the Quran says that God required the angels to bow down to Adam, precipitating the rebellion of Iblis.
Adam is also the first of the prophets ( nabi ), for he received the first revelation from God. Adam is called in the Quran khalifah , or vice-regent, meaning that it belongs to him and his progeny to both use creation for their benefit and to develop it according to God's will (2:30). In some hadith Adam is said to be made "in the image of God". This has been suggestive for Muslims, especially for mystics, of the spiritual journey each person should undertake.
Orthodox Muslim commentators are clear in saying that unlike God Adam has no creative power, only the power to submit to or to disrupt God's created order. Perhaps most critically Adam and his progeny are characterized with the term fitrah , a word which suggests that their whole being is in accord with God's creative purpose.
Although there are differences of opinion among Muslim commentators as to the spiritual and legal implications of fitrah , all emphasize that humans are by nature capable of knowing and obeying the will of God. Indeed one Quranic verse (7:172), which also emphasizes human responsibility, states that God confronted all of the souls of all potential humans, and that they acknowledged Allah as their Creator, thus they have no excuse at the judgement for having failed to recognize him as such.
This leads to their punishment, and equally to their repentance, and then a more mature understanding of Allah as the ultimate reality. The event defines what Muslims see as the fundamental human fault, which is forgetting Allah's command.
