Mishkat al-Masabih 8 The Excellent Qualities of the Qur’an كتاب فضائل القرآن 43

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: ” إِنَّ سُورَةً فِي الْقُرْآنِ ثَلَاثُونَ آيَةً شَفَعَتْ لِرَجُلٍ حَتَّى غُفِرَ لَهُ وَهِيَ: (تَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ) رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ وَابْنُ مَاجَه

Abū Huraira reported God’s messenger as saying, “A sūra in the Qur’ān containing thirty verses interceded for a man till his sins were forgiven. It was ‘Blessed is He in whose hand is the kingdom.’” (Qur’ān, 67) Ahmad, Tirmidhī, Abū Dāwūd, Nasā’i and Ibn Mājah transmitted it.
