"I saw Jibreel descending from heaven, and his great size filled the space between heaven and earth." [Muslim].

"Praise be to Allah, Who created (out of nothing) the heavens and the earth, Who made the angels messengers with wings - two, or three, or four (pairs) adds to Creation as He pleases: for Allah has power over all things." [35:1]
