Abu Hurayrah reported that the Prophet (ﷺ) ﷺ said:

“There is a sūrah in the Qur'ān of thirty verses; it intercedes for a man until he is forgiven, and it is Sūrat Tabārak (Blessed Be He in Whose Hand is the Dominion).” Reference: Jami` at-Tirmidhi 2891

عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏

‏ إِنَّ سُورَةً مِنَ الْقُرْآنِ ثَلاَثُونَ آيَةً شَفَعَتْ لِرَجُلٍ حَتَّى غُفِرَ لَهُ وَهِيَ سُورَةُ تَبَارَكَ الَّذِي بِيَدِهِ الْمُلْكُ.‏
