And [mention] when We said to the angels, "Prostrate before Adam"; so (2:34)

Almuntakhab Fi Tafsir Alquran Alkarim

There and then We said to the angels: Prostrate yourselves to Adam in adoration. The angels prostrated to Adam in admiration except Iblis who declined with inordinate self-esteem. He was a disobedient rebel

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(2:34) Then We commanded the angels, "Bow yourselves to Adam. "All bowed *45 but Iblis *46 refused to do so; he waxed proud and joined the defiers. *47

And [mention] when We said to the angels, "Prostrate before Adam"; so meaning

*45). This signifies that all the angels whose jurisdiction embraces the earth and that part of the universe in which the earth is situated were ordered to devote themselves to man's service. Since man had been invested with authority on earth the angels were told that whenever man wanted to make use of the powers with which he had been invested by God, and which God of His own will had allowed him to use, they should co-operate with him and enable him to do whatever to do, irrespective of right and wrong.
This can be understood with reference to the manner in which government employees are required to work. When a sovereign appoints a governor or a magistrate, all government employees under his jurisdiction are duty not. But as soon as the sovereign indicates to those employees that the governor or magistrate should be barred from doing something, the effective authority of the governor or the magistrate comes to an abrupt end. In fact, were the sovereign to issue the order that the governor be dismissed or imprisoned, the same employees who until then had been moving to and fro at his bidding would not feel hesitant in putting hand on him and taking him to prison.
God's order to the angels to prostrate themselves before Adam was of a similar nature. It is possible that prostration signifies the fact of their becoming yoked to man's service. At the same time it is also possible that they, were ordered to perform the act of prostration itself as a sign of the envisaged relationship between angels and man. In my view the latter seems more plausible.
*46). Iblis literally means 'thoroughly disappointed; utterly in despair'. In Islamic terminology the word denotes the jinn who, in defiance of God's command, refused to obey and to yoke himself to the service of Adam and his progeny and asked God to allow him a term when he might mislead and tempt mankind to evil and error. He is also called al-Shaytan(Satan)
In fact Satan (or Iblis) is not an abstract, impersonal force. Like human beings he is possessed of a specific personality. Moreover, one should not make the mistake of considering Satan an angel. Elsewhere the Qur'an itself clearly states that he was a jinn and jinn, as we know, are an independent species, distinct from the angels. (See Qur'An 18: 50.)
*47). These words seem to indicate that in committing disobedience Iblis was probably not alone. What seems to have been the case is that a section of the jinn was bent upon rebellion and the name of Iblis is mentioned only because he was their leader and the most noted among them for his rebellion. Another translation of this sentence could be: '? and he was of the defiers (kafirin)'. If this sense is correct, these words would signify that there was already a party of rebellious and recalcitrant jinn and that Iblis belonged to that party. In the Qur'an the word shayatin (satans) denotes these jinn and their offspring. Hence, whenever the context itself does not indicate that the term has been used for human beings who possess satanic attributes, the word ' Satans' should be understood to signify these satanic jinn.
