Sahih Muslim Book 4, Hadith Number 1495.

‘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.
