It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him), as a marfu' report, that the Prophet (peace and blessings be upon him) said: "The Greatest Name of Allah, by which, when He is called upon, He answers, is in three surahs: Surah al-Baqarah, Surah Al Imran and Surah Ta Ha."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abdullah bin al-Ala' except al-Walid, and Hisham is alone in narrating it."
