This is a ‘madani’ Surah and it has 5 ayaat. It is narrated from the Holy Prophet (Sal Allaho Alehi Wasallam) that whoever recites this Surah in the month of Ramadhan in any of his prayers, it is as if he has fasted in Makkah and he will get the reward for performing Hajj and ‘Umra.

Imam Muhammad al-Baqir (a.s.) said that in the prayer of Shafa’a (in Salaatul-layl) one should recite Surah al-Falaq in the first rak’aat and an-Naas in the second.
