We call a cute little girl an angel. But i don't think that Angels are females.

angels are spiritual beings ,God messengers ....who gives us GOd messages and sumtimes help us out in our bad times..and it is never been specified that angels are always male and as little girl is a gift from God Almight which gives us the message of love so that they are called little angels.

The reason a cute little girl is referred to as an "Angel" is simple. It's what we call them out of love. Angels are considered to be pure, innocent and flawless in conduct- traits that could be attributed to a baby girl. Calling someone an Angel doesn't make them one.
This has nothing to do with Angels in reality. They aren't male or female & that's true.

It's like one of those things in our culture where a mother calls her son "Kalejay ka tukra". She calls her son so out of love and devotion... it doesn't literally make her son a piece of her liver :P lol!

Some religion follower called Angels daughters of God, thats why... Its mentioned in Quran as well

Well, angels are "innocent" and so are girls ; )

because they can make you to leave your bad things and brings you to a lightened path
