There are 40 verses in Surah an-Naba and it is a ‘makki’ surah. By ‘Makki’ it means it was revealed in mecca.
Imam Ja’far as-Sadiq (a.s.) has said that whoever recites this surah everyday will be fortunate enough to visit Masjidul Haraam in the same year by the will of Allah.
The Holy Prophet (a.s.) said that memorization of this surah carries great reward.
If this surah is recited with the intention of staying awake, then the reciter will not fall asleep and if it is recited before travelling then the journey will become easy.
