As for those who say, ‘Our Lord is Allah,’ and then remain steadfast, the angels descend on them, saying: ‘Fear ye not, nor grieve; and rejoice in the Garden that you were promised. ‘We are your friends in this life and in the Hereafter. Therein you will have all that your souls will desire, and therein you will have all that you will ask for.’
Islam, the Holy Qur’an, 41:31-32
No people gather to remember Allah Almighty but that the angels surround them, cover them with mercy, send tranquillity upon them, and mention them to Allah among those near to Him.
Islam, Saying of the Holy Prophet (sa), Sahih Muslim, Hadith 2700
God Almighty does not need anything, angels or sun or moon or stars, but He desired that His powers should be exhibited through the mediation of means so that thereby wisdom and knowledge should spread among people.
Islam, Saying of the Promised Messiah (as), The Essence of Islam – Vol. II, p. 179.
I sought the Lord, and he answered me, and delivered me from all my fears. Look to him, and be radiant; so your faces shall never be ashamed. This poor soul cried, and was heard by the Lord, and was saved from every trouble. The angel of the Lord encamps around those who fear him, and delivers them.
Judaism, The Tanakh, Psalm 34:4-7
Christianity, The Bible, Hebrews 1:14
I [the Bodhisattva Samantabhadra] relieve the distress of the beings of all evil realms, and equally bestow happiness on them. I continue to do so through the lapse of boundless kalpas, and in the extent of the ten quarters of the universe. The benefits of all are eternal, and omnipresent.
Buddhism, Gandavyuha Sutra
