حَدَّثَنَا إِسْمَاعِيلُ بْنُ إِبْرَاهِيمَ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، أَنَّ أَبَا بَكْرٍ، رَضِيَ اللَّهُ عَنْهُ خَطَبَ النَّاسَ فَقَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَا أَيُّهَا النَّاسُ إِنَّ النَّاسَ لَمْ يُعْطَوْا فِي الدُّنْيَا خَيْرًا مِنْ الْيَقِينِ وَالْمُعَافَاةِ فَسَلُوهُمَا اللَّهَ عَزَّ وَجَلَّ.
