There are 3 ayaat in this ‘makki’ Surah. Imam Ja’far as-Sadiq (a.s.) 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.
