There are thousands and thousands of accounts of people seeing angels in there heavenly forms without the belly buttons of course. In Islam we believe the same thing but I can give you hundreds of accounts of angel sitings.
Is it possible, well I am a believer for sure. Can I convince you well maybe not but I love Angels my dear. Angels are everywhere. We have Angels of the mountains, angels of the sea, angels of the road. Everyone has guardian angels. You have angels that record your deeds, you have death angel (a huge one indeed). You have angels of the throne. Angels of the grave, angels of hellfire.
Do you feel the presence of angels with you. For sure I do.
