'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 ﷺ, was better than I.

وَحَدَّثَنَاهُ عَبْدُ بْنُ حُمَيْدٍ، حَدَّثَنَا سَعِيدُ بْنُ عَامِرٍ، عَنْ شُعْبَةَ، ح وَحَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، كِلاَهُمَا عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، أَنَّ ابْنَ عَبَّاسٍ، أَمَرَ مُؤَذِّنَهُ - فِي حَدِيثِ مَعْمَرٍ - فِي يَوْمِ جُمُعَةٍ فِي يَوْمٍ مَطِيرٍ . بِنَحْوِ حَدِيثِهِمْ وَذَكَرَ فِي حَدِيثِ مَعْمَرٍ فَعَلَهُ مَنْ هُوَ خَيْرٌ مِنِّي . يَعْنِي النَّبِيَّ ﷺ .
