Sunan Ibn Majah Book 34, Hadith 31
"The Prophet (saas) heard a man say: 'Allahumma! Inni as'aluka bi-annaka Antallahul-Ahadus-Samad, alladhi lam yalid wa lam yuwlud, wa lam yakun lahu kufuwan ahad (O Allah! I ask You by virtue of Your being Allah, the One, the Self-Sufficient Master, Who begets not nor was begotten, and there is none co-equal or comparable to Him).' The Messenger of Allah (saas) said: 'He has asked Allah by His Greatest Name, which if He is asked thereby He gives, and if He is called upon thereby He answers.'"
The Greatest Name of Allah, if He is called by which He will respond, is in three Surah: Al-Baqarah, Al 'Imran and Ta-Ha. (Hasan)Another chain for something similar from Al-Qasim, from Abu Umamah, from the Prophet (saas).
"The Prophet (saas) heard a man say: 'Allahumma! Inni as'aluka bi-anna lakal-hamd. La ilaha illa Anta, wahdaka la sharika laka. Al-Mannan. Badi'us-samawati wal-ard. Dhul-jalali wal-ikram (O Allah! I ask You by virtue of the fact that all praise is due to You; none has the right to be worshiped but You alone, and You have no partner or associate, the Bestower, the Originator of the heavens and the earth, the Possessor of majesty and honor.' He (saas) said: 'He has asked Allah by His Greatest Name which, if He is asked thereby He gives and if He is called upon thereby He answers.'"
