Demonic beings are capable of disguising themselves as angels of light. How can we be sure that one of these demons wasn’t what Mohammud encountered?
In Islam we believe God created 2 types of creation on earth, the humans and the Jinn. Jinn were created from a smokeless flame of fire, living on earth, just like humans (some are believers, some are disbelievers). The first recorded jinn to be disobedient is Iblis (Satan). About Satan God revealed in the Quran:
And indeed, We created man from sounding clay of altered black smooth mud. And the jinn, We created aforetime from the smokeless flame of fire. And (remember) when your Lord said to the angels: "I am going to create a man (Adam) from sounding clay of altered black smooth mud. “So, when I have fashioned him completely and breathed into him (Adam) the soul which I created for him, then fall (you) down prostrating yourselves unto him.” So, the angels prostrated themselves, all of them together.
Except Iblîs (Satan), - he refused to be among the prostrators.
(Allâh) said: “O Iblîs (Satan)! What is your reason for not being among the prostrators?” Iblîs (Satan) said: “I am not the one to prostrate myself to a human being, whom You created from sounding clay of altered black smooth mud.” (Allâh) said: “Then, get out from here, for verily, you are Rajîm (an outcast or a cursed one). And verily, the curse shall be upon you till the Day of Recompense (i.e. the Day of Resurrection).” Iblîs (Satan) said: “O my Lord! Give me then respite till the Day they (the dead) will be resurrected.” Allâh said: “Then, verily, you are of those reprieved, Till the Day of the time appointed.” Iblîs (Satan) said: “O my Lord! Because you misled me, I shall indeed adorn the path of error for them (mankind) on the earth, and I shall mislead them all. Except Your chosen, (guided) slaves among them.” (Allâh) said: "This is the Way which will lead straight to Me. Certainly, you shall have no authority over My slaves, except those who follow you of the Ghâwîn (those who go astray, criminals, polytheists, and evil-doers, etc.) [The Noble Qur’an - Al-Hijr 15:26-42]
There are many lessons to be taken from these verses regarding the story of Satan, but im quoting them to illustrate how Satan became what he is. Those that assist Satan in misguiding humans are called Shayateen (devils). They are the disbelieving disobedient Jinn.
Angels were created from Light. They have no gender, and are always obedient to God and carry out God’s commandments in nature and the universe. Although Angels are invisible, they do have the ability to appear to humans, usually to the Prophets and Messengers.
Contrary to christian beliefs, in Islam theres no such thing as ‘fallen Angels’ because Angels were created by God to be completely obedient, thus it is impossible for them to disobey or disbelieve in God.
The Angel in charge of revelation is Gabriel, the angel that came to all the Prophets including Muhammed with revelation. Although he can take many forms, the Angel Gabriel in his original form has been described by the Prophet Muhammed as having six hundred wings, each of which were covering the horizon when he saw him. Some of the attributes Angels possess include greatness in size, wings, abundantly beautiful, able to take on different forms, very powerful, and faster than any speed known to man.
Im narrating all this info about Angels to illustrate neither Satan nor the devils can take the form of Angels. As i clarifed earlier, Satan is a Jinn, made of flameless fire. Although Jinn are concealed from being seen by humans in their original form, they have the ability to take the form of people and animals, but they cannot take the form of Angels.
Ibn Taymiyah (one of the great scholars of Islam) said:
The jinn may appear in human and animal form, so they may appear as snakes and scorpions etc, or in the form of camels, cattle, sheep, horses, mules and donkeys, or in the form of birds, or in the form of humans, as Satan came to Quraysh in the form of Suraaqah ibn Maalik ibn Ju’sham when they wanted to set out for Badr.
