Narrated Anas ibn Malik:
I was sitting with the Messenger of Allah (ﷺ) and a man was offering prayer. He then made supplication:
""'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 Thee by virtue of the fact that praise is due to Thee, there is no deity but Thou, Who showest favour and beneficence, the Originator of the Heavens and the earth, O Lord of Majesty and Splendour, O Living One, O Eternal One."""
The Prophet (ﷺ) then said: He has supplicated Allah using His Greatest Name, when supplicated by this name, He answers, and when asked by this name He gives.
