Virtues of the Qur'an's Chapters and Verses, 39

Abu Umāmah reported that the Prophet (ﷺ) ﷺ said, “Allah’s Most Magnificent name, which when used to implore Him, He responds, is found in three suwar:

Al-Baqarah, Āl-Imran, and Tāha (meaning Al-Hayy al-Qayyoom).” Reference: Sunan Ibn Majah 3856; Al-Tabarāni 7925; Al-Silsilah al-Ṣaḥīḥah 746.

اسْمُ اللهِ الأعْظَمُ الذي إذا دُعِيَ بهِ أجابَ ؛ في ثلاثِ سُوَرٍ من القُرآنِ : في ( البَقرةِ ) و( آلِ عِمْرانَ )، و( طه ).
