This is a ‘makki’ surah and it has 50 ayaat.
The Holy Prophet (s.a.w.) has said that the one who recites this surah will not be counted from the Mushrikeen (polytheists). He will always be victorious over his enemy.
It is narrated from Imam Ja’far as-Sadiq (a.s.) that drinking this surah after it is written, and then dissolved in water that is mixed with the water from an onion, acts as a cure from aches and pains.
