Angels = Shapeshifters = Not everyone on Earth is "Human"?

"There are many angels that walk amongst us in this world, unrecognized by others. Angels apparently adopt the coloration of the society into which their mission has taken them"

"It's fairly common — as far as angel encounters — to hear about “mysterious strangers” who appear in the way of beggars or homeless. This draws us to the Scripture that says, “Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it” (Hebrews 13:2)."

"When angels are seen in Scripture, they usually appear in the form of human beings, specifically as men—adult males, not women or children."

"He sent his angels to the daughters of men, that they might take some of them for themselves and raise offspring for their enjoyment. And at first they did not succeed. When they had no success, they gathered together again and they made a plan together. They created a counterfeit spirit, who resembles the Spirit who had descended, so as to pollute the souls through it. And the angels changed themselves in their likeness into the likeness of their mates (the daughters of men), filling them with the spirit of darkness, which they had mixed for them, and with evil. They brought gold and silver and a gift and copper and iron and metal and all kinds of things. And they steered the people who had followed them into great troubles, by leading them astray with many deceptions."

"The angels cannot be seen in their original form by most people unless they appear in human form.

In the answer to question no. 70364 we have explained in detail that it is impossible for most people to see the angels in their original form, and that this was not granted to anyone of this ummah (Muslim nation) except the Messenger of Allah (peace and blessings of Allah be upon him).

As for the angels appearing in human form, this is proven in the Quran and saheeh sunnah (authentic prophetic teachings). If an angel appears in human form, it is possible for everyone to see him and there is no difference between males and females, or old and young."
