The Messenger of Allah ﷺ would not sleep until he had recited [the above two Sūrahs]. (Tirmidhī 3404) The Messenger of Allah ﷺ said: “A Sūrah from the Qur’ān containing 30 verses will intercede for a man until he is forgiven. It is Sūrah al-Mulk.” (Tirmidhī 2891) ‘Abdullāh ibn Mas‘ūd (raḍiy Allāhu ‘anhu) narrated that whoever reads Sūrah al-Mulk every night, Allah will protect him from the punishment of the grave. He said: “At the time of the Messenger of Allah ﷺ, we used to call it ‘al-māni‘ah’ (the protector). Indeed there is a Sūrah in the Book of Allah [i.e. this Sūrah]; whoever recites it every night has done very well.” (Nasā’ī in ‘Amal al-Yawm wal-Laylah 711)
