Reading Surat al-Mulk protects a Muslim from the trials of the grave, but how often does one have to read it? Once a day or more?.
It was narrated from Abu Hurayrah that the Prophet (peace and blessings of Allaah be upon him) said: “A soorah from the Qur’aan containing thirty verses will intercede for a man so that he will be forgiven. It is the soorah Tabaarak Alathi bi yadihi’l-mulk [i.e., Soorat al-Mulk].”
Narrated by al-Tirmidhi, 2891; Abu Dawood, 1400; Ibn Maajah, 3786.
Al-Tirmidhi said, this is a hasan hadeeth. It was classed as saheeh by Shaykh al-Islam Ibn Taymiyah in Majmoo’ al-Fataawa, 22/277, and by Shaykh al-Albaani in Saheeh Ibn Maajah, 3053.
What is meant is that a person should read it every night, act in accordance with the rulings contained in it, and believe in the information mentioned in it.
It was narrated that ‘Abd-Allaah ibn Mas’ood said: Whoever reads Tabaarak allaahi bi yadihi’l-mulk [i.e., Soorat al-Mulk] every night, Allaah will protect him from the torment of the grave. At the time of the Messenger of Allaah (peace and blessings of Allaah be upon him) we used to call it al-maani’ah (that which protects). In the Book of Allaah it is a soorah which, whoever recites it every night has done very well.
Narrated by al-Nasaa’i, 6/179; classed as hasan by al-Albaani in Saheeh al-Targheeb wa’l-Tarheeb, 1475.
The scholars of the Standing Committee said:
One this basis there is the hope that whoever believes in this soorah and reads it regularly, seeking the pleasure of Allaah, learning the lessons contained in it and acting in accordance with the rulings contained therein, it will intercede for him [in the Hereafter].

And Allaah knows best.
