Sayyiduna Abu Hurayra (Radhiallaahu Anhu) reports that Rasulullah (Sallallaahu Alayhi Wasallam) said, 'Verily there is a Surah in the Qur'aan which has 30 Aayats. It had interceded for a person till he was forgiven. That Surah is 'Tabaaraka llaahiy biyadihil mulk'.' (Sunan Tirmidhi Hadith2891) Imaam Tirmidhi has classified this narration as Hasan (sound) and Imaam ibn Hibbaan and al-Haakim regarded it as Sahih (authentic). See Saheeh ibn Hibbaan vol.3 pg.67-69 and Mustadrak al-Haakim vol.2 pg.498 Sayyiduna ibn Mas'ood (Radhiallaahu Anhu) is reported to have said, 'A man will be approached in his grave from his legs and from his chest and then from his head. And each time this Surah will defend him by saying, 'You cannot do anything to him, he used to recite Surah Mulk'.' Sayyiduna ibn Mas'ood (Radhiallaahu Anhu) further states, 'It is called, 'Al-maani'ah'. For it protects from the punishment of the grave.' (Mustadrak al-Haakim vol.2 pg.498). imam Haakim has classified this narration as Saheeh (authentic) and Haafiz Zahabiy has confirmed this. and Allah Ta'ala Knows Best Surah Al-Mulk Surat al-Mulk (The Kingdom) This is a Makkan sura which was sent down after at-Tur (52) and before al-Haqqa ( 69). It has various names. As well being called al-Mulk, it is also called al-Waqiya (the Protector), al-Munjiyya (the Rescuer), and al-Mâni'a (the Defender) because it protects the one who knows it and rescues him from the punishment and defends him during the Rising. It is also called al-Mujadila (the Arguer) because it argues on behalf of the one who knows it when he is the grave. Numerous hadiths have mentioned its excellence. It is related in a hadith from Jabir that the Messenger of Allah, may Allah bless him and grant him peace, used to recite this sura every night when he went to bed and he said, "It rescues people from the punishment of the grave." The Prophet, may Allah bless him and grant him peace, said, "There is a sura of the Book which only has thirty ayats which will intercede for a man on the Day of Rising and will bring him out of the Fire and make him enter the Garden. It is Surat Tabarak (meaning al-Mulk)." Ibn 'Abbas said, "One of the Companions of the Messenger of Allah pitched his tent on a grave without knowing that it was a grave, and it contained a man who was reciting 'Blessed is He who has the Kingdom in His hand.' He went and told the Prophet who said, 'It is the defender. It is the protector which is protecting him from Allah's punishment.' The Messenger of Allah further said, "I wish that 'Tabarak' could be in the heart of every believer." It is related that if someone recites it every night, he will not be harmed by the tempter (fattân). "Fattân" is used for various things. It means Shaytans who tempts people and makes disobeying Allah attractive. It is used for the dirham and the dinar, meaning money, which tempts people. It is used for the angels Munkar and Nakir who question the dead in the graves. It is also used for a highwayman who attacks travellers on the road.
