What did the Mu'adhdhin of Ibn 'Abba say Adhan on Friday as mentioned by Ma'mar and others and what did the Prophet Muhammad (saw) do that was better than him?
 'Abdullah b. Harith reported that the Mu'adhdhin of Ibn 'Abba said Adhan on Friday (and then made the announcement to say prayer in houses) because it was a rainy day; as it has been narrated by Ma'mar and others, and in this hadith it was mentioned:                      He who did it, i. e. the Apostle of Allah (may peace be upon him), was better than I.
