There are 40 verses in this 'makki' surah. 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. 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. Drinking water in which this surah has been dissolved cures stomach problems.
