This Surah was revealed in Madinah and it has 18 ayaat. It is narrated from the Holy Prophet (S) that the reward for reciting this Surah can be compared to ten times the number of believers and disbelievers on Earth. Imam Ja’far as-Sadiq has narrated that those who recite this Surah will be counted from among those who visited the Holy Prophet (S). Writing this Surah and keeping it in one’s possession makes the Shaitan run away and acts as a protection in times of war and unrest. If a pregnant woman drinks water in which this Surah has been dissolved, then both herself and her child will remain safe from danger and drinking this water also increases breast-milk in a breastfeeding mother.
