So this Surah is a shield, as it shields a person from the punishment of the grave. In the Tawrāt [Torah] its name is Surah Al-Mulk, and whoever recites it at night performs a remarkably pious action.

An Angel will make him recite Quran in the grave

The Beloved and Blessed Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has said: Whoever started reciting the Holy Quran and dies before learning it by heart, an angel will teach him the Holy Quran in his grave so that he will meet Allah عَزَّوَجَلَّ in a such a state that he will have memorized the whole Quran.

10. Blessing of the blessed Surah Yaseen

In Yemen, after burying a deceased person, when people started leaving the graveyard, they heard a noise of someone being beaten in a grave. Then all of a sudden a black dog appeared from a grave. A man asked: Who are you? It replied: I am the bad deeds of the deceased. It was asked: Who was being beaten—you or the deceased? It said: I was being beaten; Surah Yaseen and other Surahs were beside him; they came between him and me and drove me out.

(Sharh-us-Sudoor, pp. 186)

Surah As-Sajdah will intercede

Sayyiduna Khaalid Bin Ma’daan Taabi’i رَضِىَ اللهُ تَعَالٰی عَـنْهُ has narrated that Surah As-Sajdah will fight for its reciter in the grave and will humbly say: Ya Allah عَزَّوَجَلَّ! If I am from Your book, then please accept my intercession on behalf of him and if I am not from Your book, then erase me from Your book. Surah As-Sajdah will be like a bird that will spread its wings upon its reciter; it will intercede on behalf of him and will save him from the punishment of the grave.
