Faith in angels is the common pillar and basis of faith in the divine religions, namely Judaism, Christianity and Islam. The fact that the faith in angels is the subject of faith in religions based on revelation is also important in terms of showing that they stem from the same source. On the other hand, faith in angels shows that the Prophet Muhammad (saw) is the Messenger of Allah (swt) and Islam is the last divine religion. (Ali Erbaş, “Melek”, DİA, XXIX, 37-39) Because in all divine religions, it is emphasized that angels have various responsibilities. In this context, some of the duties of angels in Judaism are mentioned, such as being at God's command, worshiping Him, performing tabligh, protecting and helping people. In Christianity, it is stated that angels have duties such as glorifying and praising God, conveying God's commands to people, protecting and helping people, and ensuring the administration of nature. (Erbaş, “Melek”, DİA, XXIX, 37-39) In addition, in the sacred texts of both religions, it is emphasized that the number of angels is quite high.(Komisyon, Hadislerle İslam, I, 53)

Throughout history, many civilizations such as Babylon, Sumer, Assyria, and Hittites have come and gone, and each community has had its own beliefs and acceptances. However, one of the most important common aspects of these civilizations is the deep respect or fear they show to the spirits they consider sacred, especially angels. Various manifestations of this are clearly seen in the written or oral sources of these civilizations. (Erbaş, Melekler Alemi, s. 53 vd.)  Likewise, there are clear examples of the faith in angels in the religions of the Far East and Ancient Iran. Therefore, faith in angels can be seen in Zoroastrianism, religions of India and Taoism. (Erbaş, “Melek”, DİA, XXIX, 37-39)

There was also the faith of angels in the society of Jahiliyyah, to which the Prophet Muhammad (saw) was sent, but it was founded on wrong foundations. Because the Meccan mushriks described an­gels as "daughters of Allah". On the other hand, with these expressions in the following verse, Almighty Allah (swt) points out the ungroundedness of their claims and their rejection: “So inquire of them, [O Muhammad], "Does your Lord have daughters while they have sons? Or did We create the angels as females while they were witnesses?" Unquestionably, it is out of their [invented] falsehood that they say," Allah has begotten," and indeed, they are liars. ” (Saffat, 37/149-152)

Faith in angels is one of the pillars of iman (faith) in Islam Although it is an independent pillar, it has a very close connection with other pillars of faith. First of all, faith in angels requires faith in Allah (swt) and the order He has placed in the universe. Angels are also in charge of the order that Allah (swt) has created in the universe, and they fulfill the task ordered to them in the order of the universe without interruption. 

Islam aims to ensure the happiness of people in this world and in the Hereafter. For this, Islam clearly states the necessary rules so that they can find the right way. In this context, one of the things that must be believed in the Qur'an is faith in angels. As a matter of fact, it is clearly emphasized in a verse that faith in angels is one of the principles of faith: “The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allah and His angels and His books and His messengers,” (Baqarah, 2/285) In another verse, it is warned that denying angels will lead a person to dalalah. “O you who have believed, believe in Allah and His Messenger and the Book that He sent down upon His Messenger and the Scripture which He sent down before. And whoever disbelieves in Allah, His angels, His books, His messengers, and the Last Day has certainly gone far astray.” (Nisa, 4/136) Faith in angels is also an indication of belief in the ghaib, which is one of the basic characteristics of believers who are faithfully attached to Allah (swt). (Nisa, 4/136.)

Prophet Muhammad (saw), sent by Almighty Allah (swt) as the last prophet to humanity, also pointed out the necessity of faith in angels. In this context, in the narrative known as the Hadith of Jibril, Prophet Muhammad (saw) mentioned faith in the angels while enumerating the pillars of faith. (Muslim, Iman, 5)
