Surah as Sajdah is Surah Number 32 in Holy Quran.
There are 30 verses in this Surah and it was revealed in Makkah. Some scholars say that the 19th, 20th and 21st ayaat of this Surah are ‘madani’. In the commentary of Burhan it is narrated from the Holy Prophet (Sal Allaho Alehi Wasallam) that the reward for reciting Surah as-Sajdah and Surah al-Mulk is the same as what reward is gotten if one spends the entire night of Qadr in worship. It is said that the Holy Prophet (Sal Allaho Alehi Wasallam) used to recite these Surahs before sleeping.
The person who recites this Surah will be given 60 rewards, forgiven 60 sins and raised 60 levels nearer to Allah (S.w.T.). Imam Ja’far as-Sadiq (a.s.) has said that one who recites this Surah will be given his book of deeds in his right hand on the Day of Judgement and will be counted from among the friends of the Holy Prophet (Sal Allaho Alehi Wasallam) and his family. Keeping this Surah in writing works as a cure from aches and pains.
