Narrated Muhammad bin Seereen:
حَدَّثَنَا مُسَدَّدٌ ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ ، قَالَ أَخْبَرَنِي عَبْدُ الْحَمِيدِ ، صَاحِبُ الزِّيَادِيِّ قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْحَارِثِ ابْنُ عَمِّ، مُحَمَّدِ بْنِ سِيرِينَ قَالَ ابْنُ عَبَّاسٍ لِمُؤَذِّنِهِ فِي يَوْمٍ مَطِيرٍ إِذَا قُلْتَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ. فَلاَ تَقُلْ حَىَّ عَلَى الصَّلاَةِ. قُلْ صَلُّوا فِي بُيُوتِكُمْ. فَكَأَنَّ النَّاسَ اسْتَنْكَرُوا، قَالَ فَعَلَهُ مَنْ هُوَ خَيْرٌ مِنِّي، إِنَّ الْجُمُعَةَ عَزْمَةٌ، وَإِنِّي كَرِهْتُ أَنْ أُخْرِجَكُمْ، فَتَمْشُونَ فِي الطِّينِ وَالدَّحْضِ.
On a rainy day Ibn `Abbas said to his Mu'adh-dhin, "After saying, 'Ash-hadu anna Muhammadan Rasulullah' (I testify that Muhammad is Allah's Messenger (ﷺ)), do not say 'Haiya 'Alas-Salat' (come for the prayer) but say 'Pray in your houses'." (The man did so). But the people disliked it. Ibn `Abbas said, "It was done by one who was much better than I (i.e. the Prophet (p.b.u.h) ). No doubt, the Jumua prayer is compulsory but I dislike to put you to task by bringing you out walking in mud and slush."
