Hazrat Buraidah Aslami Radiallahu anhu narrates that the Messenger of Allah صلى الله عليه وسلم heard a man supplicating to Allah in these words:
*اللَّهُمَّ إِنِّي أَسْأَلُكَ بِأَنِّي أَشْهَدُ أَنَّكَ أَنْتَ اللَّهُ لَا إِلَهَ إِلَّا أَنْتَ الْأَحَدُ الصَّمَدُ الَّذِي لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ*
O Allah! I ask of You by the means of my testimony of faith and witness that You are my Allah; there is no one worthy of worship except You, nor is anyone worthy of obedience or the fulfillment of needs except You. Who is One and Alone; the entire universe is dependent upon Him, but He is not dependent on anyone; He has no children, nor is He the offspring of anyone, and there has never been, nor can there ever be, anyone else like Him or equal to Him.
Then the Messenger of Allah صلى الله عليه وسلم said: 'By Him in Whose Hand is my soul! Surely, this person has asked Allah by His Greatest Name (Ism-e-Azim), through which, if He is called upon, He responds, and if He is asked for something, He grants it.
