"There is a surah in the Qur'an, with thirty verses, which will intercede for its companion (the one who recites it) until he is forgiven: Tabarakal-ladhi bi yadihil mulk (Blessed is He in Whose Hand is the Dominion)." (Using translation from Ibn Mājah 3786)   

عَنْ رَسُولِ اللهِ ﷺ قَالَ إِنَّ سُورَةً فِي الْقُرْآنِ ثَلَاثِينَ آيَةً شَفَعَتْ لِصَاحِبِهَا حَتَّى غُفِرَ لَهُ {تَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ} [الملك 1] فَأَقَرَّ بِهِ أَبُو أُسَامَةَ وَقَالَ نَعَمْ  

[Machine] Whoever recites, "Blessed is He in whose hand is the dominion" [Surah Al-Mulk, verse 1] every night, Allah will protect him from the punishment of the grave. During the time of the Messenger of Allah ﷺ , we used to call it the preventive surah. It is indeed a chapter in the Book of Allah that whoever recites it every night will have increased blessings and goodness.  

مَنْ قَرَأَ {تَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ} [الملك 1] كُلَّ لَيْلَةٍ مَنَعَهُ اللهُ بِهَا مِنْ عَذَابِ الْقَبْرِ وَكُنَّا فِي عَهْدِ رَسُولِ اللهِ ﷺ نُسَمِّيهَا الْمَانِعَةَ وَإِنَّهَا فِي كِتَابِ اللهِ سُورَةٌ مَنْ قَرَأَ بِهَا فِي كُلِّ لَيْلَةٍ فَقَدْ أَكْثَرَ وَأَطَابَ مُخْتَصَرٌ  

"The Messenger of Allah used to fast until we said: 'He does not want to break his fast.' And he used not to fast until we said: 'He does not want to fast."' (Using translation from Nasāʾī 2347)   

كَانَ رَسُولُ اللهِ ﷺ يَصُومُ حَتَّى نَقُولَ مَا يُرِيدُ أَنْ يُفْطِرَ وَيُفْطِرُ حَتَّى نَقُولَ مَا يُرِيدُ أَنْ يَصُومَ وَكَانَ يَقْرَأُ فِي كُلِّ لَيْلَةٍ بَنِي إِسْرَائِيلَ وَالزُّمَرَ  

The Messenger of Allah ﷺ used to recite al-Musabbihat before going to sleep, and say: They contain a verse which is better than a thousand verses. (Using translation from Abū Dāʾūd 5057)  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ الْمُسَبِّحَاتِ قَبْلَ أَنْ يَرْقُدَ وَيَقُولُ «إِنَّ فِيهَا أَيَّةً أَفْضَلَ مِنْ أَلْفِ آيَةٍ»  

that the Prophet ﷺ would recite the Musabbihat (Chapters 17, 57, 59, 61, 62, 64 & 87) before sleep and say "Indeed there is an Ayah in them that is better than one thousand Ayat." (Using translation from Tirmidhī 2921)   

أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ الْمُسَبِّحَاتِ قَبْلَ أَنْ يَرْقُدَ وَقَالَ «إِنَّ فِيهَا آيَةً خَيْرًا مِنْ أَلْفِ آيَةٍ» [264] خَالَفَهُ مُعَاوِيَةُ بْنُ صَالِحٍ  

[Machine] The Messenger of Allah ﷺ used to not sleep until he recited the Tasbeehaat and said, "Indeed, in them is a verse like a thousand verses." Muawiyah said, "Indeed, some of the scholars used to consider the Tasbeehaat to be six: Surah Al-Hadeed, Surah Al-Hashr, Surah Al-Hawariyun, Surah Al-Jumu'ah, Surah Al-Taghabun, and Surah Al-Ala." Abu Abdullah Al-Rahman said, "I found on the margin of the book with the footnotes of this Hadith a black spot, so because of that, I did not write down "haddathana" (meaning "he narrated to us").  

كَانَ رَسُولُ اللهِ ﷺ لَا يَنَامُ حَتَّى يَقْرَأَ الْمُسَبِّحَاتِ وَيَقُولُ «إِنَّ فِيهِنَّ آيَةً كَأَلْفِ آيَةٍ» قَالَ مُعَاوِيَةُ إِنَّ بَعْضَ أَهْلِ الْعِلْمِ كَانُوا يَجْعَلُونَ الْمُسَبِّحَاتِ سِتًّا سُورَةَ الْحَدِيدِ وَالْحَشْرِ وَالْحَوَارِيِّينَ وَسُورَةَ الْجُمُعَةِ وَالتَّغَابُنِ وَسَبِّحِ اسْمَ رَبِّكَ الْأَعْلَى قَالَ أَبُو عَبْدِ الرَّحْمَنِ وَجَدْتُ عَلَى حَاشِيَةِ الْكِتَابِ بِحِذَاءِ هَذَا الْحَدِيثِ سَوَادًا فَمِنْ أَجْلِ ذَلِكَ لَمْ أَكْتُبْ حَدَّثَنَا  

A man came to the Messenger of Allah ﷺ and said: Teach me to read the Qur'an, Messenger of Allah. He said: Read three surahs which begin with A.L.R. He said: My age is advanced, my mind has become dull (i.e. memory has grown weak), and my tongue has grown heavy). So he said: Then read three surahs which begin with H.M. He repeated the same words. So he said: Read three surahs which begin with the "Glorification of Allah". But he repeated the same excuse. The man then said: Teach me a comprehensive surah, Messenger of Allah. The Prophet ﷺ taught him Surah (99). "When the Earth is shaken with her earthquake". When he finished it, the man said: By Him Who sent you with truth, I shall never add anything to it. Then man then went away. The Prophet ﷺ said twice: The man received salvation. (Using translation from Abū Dāʾūd 1399)   

أَتَى رَجُلٌ رَسُولَ اللهِ ﷺ فَقَالَ أَقْرِئْنِي يَا رَسُولَ اللهِ فَقَالَ «اقْرَأْ ثَلَاثًا مِنْ ذَوَاتِ آلر» قَالَ الرَّجُلُ كَبِرَتْ سِنِّي وَاشْتَدَّ قَلْبِي وَغَلُظَ لِسَانِي؟ قَالَ «اقْرَأْ ثَلَاثًا مِنْ ذَوَاتِ حم» قَالَ مِثْلَ مَقَالَتِهِ الْأُولَى فَقَالَ «اقْرَأْ ثَلَاثًا مِنَ الْمُسَبِّحَاتِ» فَقَالَ مِثْلَ مَقَالَتِهِ الْأُولَى قَالَ لَكِنْ أَقْرِئْنِي سُورَةً جَامِعَةً فَأَقْرَأَهُ {إِذَا زُلْزِلَتِ الْأَرْضُ زِلْزَالَهَا} [الزلزلة 1] حَتَّى فَرَغَ مِنْهَا قَالَ الرَّجُلُ وَالَّذِي بَعَثَكَ بِالْحَقِّ لَا أَزِيدُ عَلَيْهَا أَبَدًا فَقَالَ رَسُولُ اللهِ ﷺ «أَفْلَحَ الرُّوَيْجِلُ أَفْلَحَ الرُّوَيْجِلُ»
