3) Chapter: Whoever raises his voice in (conveying) knowledge
Narrated `Abdullah bin `Amr:
Once the Prophet (ﷺ) remained behind us in a journey. He joined us while we were performing ablution
for the prayer which was over-due. We were just passing wet hands over our feet (and not washing
them properly) so the Prophet (ﷺ) addressed us in a loud voice and said twice or thrice: "Save your heels
from the fire."
3) باب مَنْ رَفَعَ صَوْتَهُ بِالْعِلْمِ
حَدَّثَنَا أَبُو النُّعْمَانِ، عَارِمُ بْنُ الْفَضْلِ قَالَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ أَبِي بِشْرٍ، عَنْ يُوسُفَ بْنِ مَاهَكَ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ تَخَلَّفَ عَنَّا النَّبِيُّ صلى الله عليه وسلم فِي سَفْرَةٍ سَافَرْنَاهَا، فَأَدْرَكَنَا وَقَدْ أَرْهَقَتْنَا الصَّلاَةُ وَنَحْنُ نَتَوَضَّأُ، فَجَعَلْنَا نَمْسَحُ عَلَى أَرْجُلِنَا، فَنَادَى بِأَعْلَى صَوْتِهِ . مَرَّتَيْنِ أَوْ ثَلاَثًا. " وَيْلٌ لِلأَعْقَابِ مِنَ النَّارِ "
