Musnad Ahmad Hadith 12205

It is narrated from Anas (may Allah be pleased with him) that once the Prophet (ﷺ) heard a man supplicating in this manner: ( اللَّهُمَّ إِنِّي أَسْأَلُكَ بِأَنَّ لَكَ الْحَمْدَ لَا إِلَهَ إِلَّا أَنْتَ وَحْدَكَ لَا شَرِيكَ لَكَ الْمَنَّانَ بَدِيعَ السَّمَوَاتِ وَالْأَرْضِ ذَا الْجَلَالِ وَالْإِكْرَامِ ) "O Allah! I ask You because all praise is for You alone, there is no deity except You, You are alone, You have no partner, the Most Gracious, the Originator of the heavens and the earth without any precedent, the Possessor of Majesty and Honor." The Prophet (ﷺ) said: "You have supplicated to Allah with His Greatest Name; when supplication is made with it, Allah surely accepts it, and when asked by it, He surely grants."
