Musnad Ahmad Hadith 22965

It is narrated from Buraidah (may Allah be pleased with him) that once he went out at night and met the Noble Prophet (ﷺ). The Noble Prophet (ﷺ) took his hand and entered the mosque. Suddenly, the voice of a man reciting the Qur'an was heard. The Noble Prophet (ﷺ) said, "Do you think he is a show-off?" Buraidah (may Allah be pleased with him) remained silent. That man was supplicating: "O Allah! I ask You because I bear witness that You are Allah, there is no deity except You, You are One, Self-Sufficient, He begets not, nor is He begotten, and there is none like unto Him." The Noble Prophet (ﷺ) said, "By Him in Whose hand is my soul, he has asked Allah by His Greatest Name; when He is asked by it, He surely gives, and when supplicated by it, He surely answers."
