Wikipedia - Angels are spiritual beings often depicted as messengers of God in the Hebrew and Christian Bibles along with the Quran. The English word angel is derived from the Greek ???????, a translation of ???? (mal'akh) in the Hebrew Bible (Tanakh); a similar term, ?????? (Mal??kah), is used in the Qur'an. The Hebrew and Greek words originally mean messenger. The term "angel" has also been expanded to various notions of spiritual beings found in many other religious traditions. Other roles of angels include protecting and guiding human beings, and carrying out God's tasks.
