I'm sure a small one landed on my shoulder the other day and was blowing into my ear :cool:

and just remember that satan has his angels too and so not all angels are good !
I do not know if any Muslims already answered this, but I will add this too:
Angels, according to Islaam, are made of Noor (the holy light). They have no genders, it is believed, but can appear in human form. They have wings, and depending on their status, they may have two, three, four wings. They are good beings who only follow what is commanded to them by God Almighty (cannot sin because they were not granted free will), they praise Him constantly.
