From Association of Independent Readers and Rootworkers
This 'madani' surah has 12 ayaat. It is narrated from the Holy Prophet (s.a.w.) that the one who recites this surah will be from those who always seek sincere repentance from Allah (s.w.t.). The recitation of this surah and drinking of its water acts as a cure from many ailments and diseases.
If this surah is recited by a person who is not getting sleep then he will be able to sleep and if recited by a person who is frightened, he will become calm. Frequent recitation also helps a person who is in debt to clear his debts.
