Mishkat al-Masabih #763

Anas said that a man came panting and entered the row of worshippers and said, “God is most great. Praise be to God, much, good and blessed.” When God’s Messenger finished his prayer he asked, “Which of you is the one who spoke the words?” but the people remained silent. He asked again, and when they still kept silence, he said, “Which of you said them? He said nothing wrong.” Then a man said, “I came and had difficulty in breathing, so I said them.” He replied, “I saw twelve angels racing one another to be the one to take them up to God.” Muslim transmitted it.
