Allah subhanahu wa ta'ala is the creator of everything that we see with our eyes and that which is invisible to our eyes. First the universe was created, then man was made a nation. From the beginning there was nothing but the one and only God. In order to express His existence, greatness, and power, God Almighty created the heavens, the Earth, and its riches and plants out of nothing. He made the angels, men and jinns, who were commanded to obey and worship only God alone.
Angels are invisible beings, created from light, and are free from eating, drinking, and sensual pleasures because they have no lust.
Gabriel is the most beautiful and the greatest of angels.
