What is the authentication of the supplication: "O Allah, O Living, O Self-Subsisting, O Possessor of Majesty and Honor, I ask You by Your Greatest, Good, Blessed Name, the most beloved to You, by which if You are supplicated You respond..."?

No Hadith (definition) has been found that collects this supplication, though some of its phrases are present in different Hadiths. It is permissible to supplicate with it, as long as it is not believed to have a special merit. We hope that Allah answers whoever supplicates with it, for the Messenger of Allah, peace and blessings be upon him, said: "The supplication of anyone of you is granted as long as he does not supplicate for a sin or for cutting off the ties of kinship, and as long as he does not become impatient."
