Sahih al-Bukhari, Hadith 68 ⓘ
Narrated Ibn Mas`ud: The Prophet used to take care of us in preaching by selecting a suitable time, so that we might not get bored. (He abstained from pestering us with sermons and knowledge all the time).
حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ أَبِي وَائِلٍ، عَنِ ابْنِ مَسْعُودٍ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَتَخَوَّلُنَا بِالْمَوْعِظَةِ فِي الأَيَّامِ، كَرَاهَةَ السَّآمَةِ عَلَيْنَا.
