The saints of Islam (may God have mercy on them) fly in the air, walk on water, visit the heavens as they wish, say "be" to a thing and it will be, etc...They come on earth after Muhammad (peace be upon him and his family) and his Companions (may God be well pleased with them) at each century, until the end of time, because Muhammad came on earth as the very last of all prophets, and there is no prophet after him.
