Which Sura is the delivering/saving one?

It has been mentioned in narrations that two surahs from the Qur’an are named "Al-Munjiyah" (The Deliverer): "Alif Lam Mim Tanzil" (Surah As-Sajdah) and "Tabarak Al-Mulk" (Surah Al-Mulk). In Sunan ad-Darimi, it is stated that Surah As-Sajdah intercedes for its reciter and seeks forgiveness for him, while in Sunan At-Tirmidhi, it is mentioned that Surah Al-Mulk prevents the torment of the grave and delivers from it. Surah Al-Mulk has become well-known in books of tafsir by names such as Al-Munjiyah (The Deliverer), Al-Mani'ah (The Preventer), and Al-Waqiyah (The Protector).
