It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him), he said that a man said (in prayer) in the presence of the Prophet (peace and blessings of Allah be upon him): "All praise is for Allah alone, such praise that is very pure and blessed." The Prophet (peace and blessings of Allah be upon him) said: "Who is the person who uttered these words?" The man remained silent and thought that perhaps he had suddenly said something which the Prophet (peace and blessings of Allah be upon him) disliked. The Prophet (peace and blessings of Allah be upon him) asked again: "Who is he? He has indeed spoken rightly." The man said: "I said it, and my intention was also good." The Prophet (peace and blessings of Allah be upon him) said: "By Him in Whose hand is my soul, I saw thirteen angels competing with each other as to who among them would take these words up to Allah, the Mighty and Majestic."
