Sayyiduna Abu Hurayra رضي الله عنه reports that Rasulullah
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
The Prophet (salAllahu alayhi wasalam) said 'There is a surah in the Qur'an which is only thirty verses. It defended whoever recited it until it puts him into paradise' i.e. Surah al Mulk
[Fath al Qadir 5/257, Sahihul Jamiea 1/680, Tabrani in Al-Awsat & Ibn Mardawaith]
The Prophet (salAllahu alayhi wasalam) said 'Surah al Mulk is the protector from the torment of the grave'
[Sahihul Jamiea 1/680, Hakim 2/498 & Nasai]
Jabir(radiAllahu anhu) said it was the custom of the Prophet (salAllahualayhi wasalam) not to go to sleep until he had read TabarakallahiBiyadihil Mulk and Alif Laam Meem Tanzeel.
[Ahmad, Tirmidhi and Darami]
Anas (radiAllahu anhu) reported Rasulullah (sallallahu alaiyhi wasalam) as saying, "There is a Surah which will plead for its reciter till it causes him to enter paradise (Tabarakallahi Biyadihil Mulk)."
[at-Tabrani]
Abdullah Ibn 'Abbas (radiAllahu anhu) reported that the Prophet (salAllahualayhi wasalam)said, 'It is my desire/love that Surahtul Mulk should be in the heart of every Muslim'
[Hakim, al-Hisnul Haseen by the cassical scholar Muhammad al-Jazri]
Ibn Abbas (radiAllahu anhu) said that one of the Prophet (salAllahu alayhiwasalam)'s companions set up his tent over a grave without realising that it was a grave and it contained a man who was reciting the Surah Tabarakallahi Biyadihil Mulk up to the end. He went and told the Prophet (salAllahu alayhi wasalam) who said, 'It is The Defender; it is The Protector which safeguards from Allah Ta'ala's punishment'
[at-Tirmidhi]
Khalidbin Madam (tabie) said about surat Al Mulk and 'As Sajda that these two surahs will fight for their reciter in the grave and will say, 'O Allah! If we belong to your book, accept our intercession in his favour. In case we do not, get us obliterated. These surahs will spread their wings like birds and will save the person from the torment of the grave.'
[Mishkat al-Misbah]
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 رضي الله عنه 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.
It was narrated that Abdullah ibn Mas'ud said: Whoever reads Tabarakallahi Biyadihil Mulk [i.e. Surah al-Mulk] every night,Allah will protect him from the torment of the grave. At the time of the Messenger of Allah
we used to call ital-mani'ah (that which protects). In the Book of Allah it Is a surah which, whoever recites it every night has done very well
