Al-Mominun (Arabic: المؤمنون, "The Believers") is the 23rd chapter (sūrah) of the Qur'an with 118 verses (āyāt). Regarding the timing and contextual background of the supposed revelation (asbāb al-nuzūl), it is an earlier "Meccan / Makki surah", which means it is believed to have been revealed in Mecca (Makkah), instead of later in Medina.
This surat deals with the fundamentals of faith (Aqidah), Tawheed (Islamic monotheism), Risalah (Messengership), Resurrection and the supreme Judgement of God. The surah (sorat) 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.
The theme of Risalah is emphasized with reference to the accounts of some prophets of Islam such as Nuh (Noah), Hud, 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 Meccan leaders to the message delivered to them by Muhammad (PBUH). The Sura 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.
The Surah begins with an assertion, "Most certainly the Believers have attained true success", intending to put across a point that the criterion of success and failure which people who disbelieve in Islam, hold in mind is in fact erred because it is based on misconceptions and is transitory and limited in nature, in turn leading to eventual failure and not true success.
On the contrary, those who follow the teachings of Islam taught by Muhammad, regarded by the disbelievers as failures are actually the ones who are truly successful. Because by their acceptance of the invitation to Islam, they are guaranteed of true success and everlasting bliss in this world as well as in the Hereafter. By rejecting the message of Islam, the non-believers have incurred a profound loss and would meet with the evil consequences both in this world and the next.
This is the main theme of the Surah and the whole discourse, from the beginning to the end, is meant to impress the same.
Possess Al-Khushoo
The first quality as described in verse 2 of this Surah is, "Those who are humble in their prayers"; the Arabic word used to describe the people is 'Khashi'oon' meaning those of who possess 'Al-Khushoo'.
According to Tafsir ibn Kathir (Kasir), a classical Tafsir (i.e. a commentary of the Quran written by Islamic scholar Ibn Kathir), the Arabic word 'Khushoo' encompasses the meanings of calmness, serenity, tranquility, dignity, and humility.", while Ibn Abbas explains 'Khashi'oon' to mean, with fear and tranquility. Al-Khushoo is a necessary component of Salaah / Salaat / Salah / Namaz / Salat / Solat, however can be very easily lost. In a hadith (hadees / hadis), Muhammad (PBUH) said "The first thing to be lifted up (taken away) from this Ummah will be al-Khushoo; until you will see n o one who has al-Khushoo."
It is narrated from Imam Jafar as Sadiq (a.s.) that whoever recites this Surah on every Friday, he will have a great status in the hereafter and will be in the company of prophets.
