This surah was revealed in Makkah and it has 30 ayaat.
It is also called Munjiyah because it saves the one who recites it from the torment of the grave.
The Holy Prophet (s.a.w.) likened the recitation of this surah to the staying awake on the night of Qadr. He (s.a.w.) also wished that every believer would memorize this surah and know it by heart. He said that this surah will remove its reciter from Hellfire and take him to Jannah.
Imam Ja’far as-Sadiq (a.s.) said that reciting this surah at night keeps one under the protection of Allah (s.w.t.) until morning.
Recitation on the night of Eid gives the reward of staying awake the whole night in worship.
If recited on a person who has just died, his soul gets immediate relief. Memorizing this surah has great reward.
If memorized, this surah acts as a protection from the torment of the grave, and it intercedes on behalf of the one who has memorized it on the Day of Judgement.
