Angels also visited Abraham in human form. Similarly, angels come to Lot to deliver him from danger in the form of handsome, young man.
Gabriel used to visit Prophet Muhammad (Peace Be Upon Him) in different forms. Sometimes, he would appear in the form of one of his handsome disciples, and sometimes in the form of a desert Bedouin. Angels have the ability to take human forms in some circumstances involving common people. Gabriel is God’s heavenly messenger to mankind, He would convey the revelation from God to His messengers.
Allah, the Exalted, says: “Whoever is an enemy to Gabriel (let him die in his fury), for indeed he has brought it (this Qur’an) down to your heart byAllah’s Permission ...” Qur’an 2:97
Some angels are put in charge of executing God’s law in the physical world. Mikail is responsible for rain, directing it wherever God wishes. He has helpers who assist him by the command of his Lord; they direct the winds and clouds, as God wills. Another is responsible for blowing by the Horn, which will be blown by Israfeel at the onset of the Day of Judgment. Others are responsible for taking souls out of the bodies at the time of death: the Angel of Death and his assistants.
Allah, the Exalted, says: “Say: ‘The Angel of Death, who is set over you, will take your souls. Then you shall be brought to your Lord.” Qur’an 32:11
Then there are guardian angels responsible for protecting the believer throughout his life, at home or traveling, asleep or awake. Others are responsible for recording the deeds of man, good and bad. These are known as the “honorable scribes.” Two angels, Munkar and Nakeer, are responsible for testing people in the grave. Among them are keepers of Paradise and the nineteen ‘guards’ of Hell whose leader is named ‘Malik’. There are also angels responsible for breathing the soul into the fetus and writing down its provisions, life-span, actions, and whether it will wretched or happy. Some angels are roamers, traveling around the world in search of gatherings where God is remembered.
There are also angels constituting God’s heavenly army, standing in rows, they never raise their heads, always worshipping God. As we learn from above, the angels are a grandiose creation of God, varyng in numbers, roles and abilities.
God is in no need of these creatures, but having knowledge and belief in them adds to the awe that one feels towards God, in that He is able to create as He wishes, for indeed the magnificence of His creation is a proof of the magnificence of the Creator.
