‘Alqama b. Abu Waqqas said:
I was with Mu'awiyah when his mu’adhdhin called the adhan, and Mu'awiya repeated the mu’adhdhin’s words, but when he said, “Come to prayer, he said, “There is no might and no power except in God,” and when he said, “Come to salvation,” he said, “There is no might and no power except in God the High, the Mighty.” After that he repeated the mu’adhdhin’s words, then said, “I heard God’s Messenger say that.”
Ahmad transmitted it.
