Qur'anic verses - Creation of first Man:

It would seem that the angels, though holy and pure, and endued with power from God, yet represented only one side of Creation. We may imagine them without passion or emotion, of which the highest flower is love. If man was to be endued with emotions, those emotions could lead him to the highest and drag him to the lowest. The power of will or choosing would have to go with those emotions. This power of will (when used aright) gave him to some extent a mastery over his own fortunes and over nature, thus bringing him nearer to the God-like nature, which has supreme mastery and will. We may suppose the angels had no independent wills of their own: their perfection in other ways reflected God's perfection but could not raise them to the dignity of vicegerency. The perfect vicegerent is he who has the power of initiative himself, but whose independent action always reflects the will of his principal. The distinction is expressed by Shakespeare (Sonnet 94) in those fine lines: "They are the lords and owners of their faces. Others but stewards of their excellence." The angels in their one-sidedness saw only the mischief consequent on the misuse of the emotional nature by man. The question the angels raised reflects their imperfection of knowledge but no fault of their own.
