Servants of Allah who glorify Him and carry out His commands, the angels prostrated to Adam at His order, and they must not be worshipped; believing in them is an obligation. These verses show them invoking blessings on the believers and asking forgiveness for them, and recall that some were sent with glad tidings to Abraham, Zechariah or Mary.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
[Remember] when you were asking help of your Lord, and He answered you, "Indeed, I will reinforce you with a thousand from the angels, following one another."
[Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip."
It is He who confers blessing upon you, and His angels [ask Him to do so] that He may bring you out from darknesses into the light. And ever is He, to the believers, Merciful.
