Surah Al-Mu’minoon (Arabic: سورة المؤمنون‎) (The Believers) is the 23rd Surah (chapter) of the Qur'an with 118 ayat (verses).

This Surah deals with the fundamentals of faith (Aqidah), Tawheed (Islamic Monotheism), Risalah (Messengership), Resurrection and the supreme Judgement of God. The Surah drives these themes home by drawing attention to God's creation of man through different stages in the mother's womb, His creation of the heavens and the earth, His sending down rains and growing plants, trees and fruits, and His providing of domestic animals with various benefits for man, all together with an emphasis on the fact that man shall die and shall be raised up on the Day of Resurrection. (See also: Islamic eschatology)

The theme of Risalah is emphasized with reference to the accounts of some Islamic Prophets like Nuh (Noah), Hud (Judah), Musa (Moses) and Isa (Jesus), noting that all of them delivered the same message of monotheism, but were disbelieved and opposed by the people they preached to, and that all of them were helped and rescued by Allah. A reference is also made to the similar unbelief and opposition of the Makkan leaders to the message delivered to them by Prophet Muhammad Salallahhu'alaihi Wassalam. The Surah ends with another reference to the inevitability of the Day of Resurrection and pointing out that man will not have a second chance to return to the worldly life and make amends for his lapses and mistakes.
