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)
Abu Hurayrah reported God’s messenger as saying, “A sura in the Qur’an containing thirty verses interceded for a man till his sins were forgiven. It was ‘Blessed is He in whose hand is the kingdom.’” (Qur’an, 67) Ahmad, Tirmidhi, Abu Dawud, Nasai and Ibn Majah transmitted it.
