that 'Aishah said: "The Messenger of Allah ﷺ did not speak quickly like you do now, rather he would speak so clearly, unmistakably, that those who sat with him would memorize it."  

مَا كَانَ رَسُولُ اللَّهِ ﷺ يَسْرُدُ سَرْدَكُمْ هَذَا وَلَكِنَّهُ كَانَ يَتَكَلَّمُ بِكَلاَمٍ بَيْنَهُ فَصْلٌ يَحْفَظُهُ مَنْ جَلَسَ إِلَيْهِ  

that the Messenger of Allah ﷺ would repeat a statement three times so that it could be understood.  

كَانَ رَسُولُ اللَّهِ ﷺ يُعِيدُ الْكَلِمَةَ ثَلاَثًا لِتُعْقَلَ عَنْهُ
