Sahih al-Bukhari, Hadith 616 ⓘ

Narrated `Abdullah bin Al-Harith: Once on a rainy muddy day, Ibn `Abbas delivered a sermon in our presence and when the Mu'adhdhin pronounced the Adhan and said, "Haiyi `ala-s-sala(t) (come for the prayer)" Ibn `Abbas ordered him to say 'Pray at your homes.' The people began to look at each other (surprisingly). Ibn `Abbas said. "It was done by one who was much better than I (i.e. the Prophet or his Mu'adh-dhin), and it is a license.'

حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، وَعَبْدِ الْحَمِيدِ، صَاحِبِ الزِّيَادِيِّ وَعَاصِمٍ الأَحْوَلِ عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ قَالَ خَطَبَنَا ابْنُ عَبَّاسٍ فِي يَوْمٍ رَدْغٍ، فَلَمَّا بَلَغَ الْمُؤَذِّنُ حَىَّ عَلَى الصَّلاَةِ‏.‏ فَأَمَرَهُ أَنْ يُنَادِيَ الصَّلاَةُ فِي الرِّحَالِ‏.‏ فَنَظَرَ الْقَوْمُ بَعْضُهُمْ إِلَى بَعْضٍ فَقَالَ فَعَلَ هَذَا مَنْ هُوَ خَيْرٌ مِنْهُ وَإِنَّهَا عَزْمَةٌ‏.‏
