Hazrat Buraidah narrates that the Noble Prophet (peace and blessings be upon him) heard a man supplicating in this manner: O Allah! I ask You by means of Your own self, for You are Allah, the One, the Self-Sufficient, Who neither begets nor is begotten, and there is none comparable to Him. So the Prophet (peace and blessings be upon him) said: This person has asked Allah by means of His Greatest Name, by which, when supplication is made, He accepts, and when something is asked, He grants it.

Hazrat Anas bin Malik (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) heard a man supplicating in this manner: O Allah! I ask You by means of this (invocation): All praise is for You alone, there is no deity except You, You are One, You have no partner, the Bestower and the Giver of honor, the Originator of the heavens and the earth, the Possessor of Majesty and Honor. So the Prophet said: Indeed, this person has asked Allah by His Greatest Name; when He is asked by it, He gives, and when supplicated by it, He answers.

Hazrat Abdur Rahman bin Sabit narrates that a supplicant made a supplication during the time of the Noble Prophet (peace and blessings be upon him). He said: O Allah! I ask You by means of Your name Allah, for there is no deity except You, the Most Merciful, the Most Compassionate, the Creator of the heavens and the earth without any precedent, and when You intend to do something, You say to it: Be, and it becomes. Upon this, the Noble Prophet (peace and blessings be upon him) said: Indeed, you (or he) have supplicated to Allah by means of His Greatest Name, the Name of Magnificence.

And at the beginning of Surah Al-Imran: Alif Lam Meem. Allah, there is no deity except Him, the Ever-Living, the Sustainer of all existence."

Hazrat Abdul Malik bin Umair narrates that a person recited Surah Al-Baqarah and Aal-e-Imran, so Hazrat Ka'b said, "Indeed, you have recited two Surahs, and in both of these Surahs there is such a name that when supplication is made by means of that name, it is accepted."
