In Islam, God created Adam (Arabic: آدم) from a handful of earth taken from the entire world, which explains why the peoples of the world are of different colours. According to the Islamic creation myth, he was the first prophet of Islam and the first Muslim. The Quran says that all the prophets preached the same faith of submission to God. When God informed the angels that he would create a vice-regent (a "khalifa") on Earth, the angels enquired, saying, "will You place therein such that will spread corruption and bloodshed?" So God showed the angels, saying, "Tell Me the names of these?" The angels had no knowledge of these, as God had not taught them. Then God allowed Adam to reveal these names to them, saying, "Did I not say to you (angels) that I know what is unseen in the heavens and the earth and I know what you (angels) reveal and what you (Satan) conceal;" the scholar Al-Tabari explained that God was referring to Iblis (Satan) of his evil plans and to the angels of their honesty.
