This is a ‘meccan’ surah. Asr means age which implies continuity of time. According to some commentators it is a reference to the period in which the Holy Prophet (s) was sent into this world to preach the religion of ALLAH (swt), Islam, so that mankind, in all ages, come out from the darkness of ignorance into the light of divine guidance and reach higher realms of spiritual bliss. Some say that it refers to afternoon prayers (salatul asr). Imam Jafar bin Muhammad as Sadiq (as) said: \"It refers to the age when the living Imam of the Ahl ul Bayt, Muhammad bin Hasan al Mahdi al Qa-im (ajtfs), will be commissioned by ALLAH (swt) to administer the society of all human beings under the law of ALLAH (swt) prescribed in the religion of Islam.\" Whether it refers to the time of the Holy Prophet (s) or his true successor who will act according to the teachings and laws he brought from ALLAH (swt) to guide mankind, those who follow them will achieve success in the life of hereafter, and those who reject them will be the losers. Imam Ja’far as-Sadiq (as) has said that the person who recites this surah in his recommended prayers will have a shining face on the Day of Judgement. The one who recites this surah will be patient in adversity and will be counted from among the people of truth. If this surah is written after ‘Isha prayers and kept, it will be a safety from the tyrant ruler in whose presence one is brought.
