Bodyguard of your Grave: Surah Al Mulk

Ibne-’Abbas Radiyallahu ‘anhuma narrates that someone, amongst the companions of Nabi Sallallahu ‘alaihi wasallam, set up his tent over a grave, without realizing that it was a grave. Suddenly he heard the person of the grave reciting Surah Mulk, upto to end of the Surah. He came to Nabi Sallallahu ‘alaihi wasallam and said: O Rasulallah I set up my tent unknowingly over a grave, and suddenly I heard someone reciting Surah Mulk up to its end. Nabi Sallallahu ‘alaihi wasallam said: It is the defender; it is the protector which safeguards him from the Punishment in the grave.
(Tirmidhi)


Abu Hurairah Radiyallahu ‘anhu narrates that Nabi Sallallahu ‘alaihi wasallam said: Indeed, there is a Surah in the Qur’an having thirty verses, which intercedes for its reciter until he is forgiven. And that Surah is: Tabarakalladhl biyadihil mulk (Surah 67).

(Tirmidhi) 

If we were to learn a verse a day from Surah Al Mulk, it wouldn't take you more than even a month to have it all memorized.

Imam Nawawi says, “One should be especially observant in reciting Surat Ya Sin (36), Surat al Waqia (56) and Surat al Mulk.(67)”
