Soorah Al-Mulk
Abu Dawood (1400) and al-Tirmidhi (2891 – and he classed it as hasan) narrated from Abu Hurayrah that the Prophet (blessings and peace of Allah be upon him) said:
“There is a soorah of the Qur’an, with thirty verses, that interceded for a man until he was forgiven; it is ‘Soorah Tabaarak Alladhi bi yadihi’l-mulk (Blessed is He in Whose Hand is the dominion)’ [al-Mulk 67:1].” It was also classed as hasan by al-Albaani in Saheeh at-Tirmidhi.
Al-Mannaawi (may Allah have mercy on him) said:
He recited it frequently, thus it kept asking Allah (to forgive him) until he was forgiven. This is encouragement to everyone to recite it regularly so as to attain its intercession.

Abu’l-Hasan al-Mubaarakfoori (may Allah have mercy on him) said:
What is meant is that reciting this soorah in this world will be a means of salvation from the punishment of the grave.
End quote from Mar‘aat al-Mafaateeh, 7/231
