باب مَا ذُكِرَ مِنْ دِرْعِ النَّبِيِّ صلى الله عليه وسلم وَعَصَاهُ وَسَيْفِهِ وَقَدَحِهِ وَخَاتَمِهِ وَمَا اسْتَعْمَلَ الْخُلَفَاءُ بَعْدَهُ مِنْ ذَلِكَ مِمَّا لَمْ يُذْكَرْ قِسْمَتُهُ، وَمِنْ شَعَرِهِ وَنَعْلِهِ وَآنِيَتِهِ، مِمَّا يَتَبَرَّكُ أَصْحَابُهُ وَغَيْرُهُمْ بَعْدَ وَفَاتِهِ
Sahih al-Bukhari 3112

Muhammad bin Suqa:

I heard Mundhir at-Tuzi reporting Ibn Hanafiya who said,

"My father sent me saying, 'Take this letter to `Uthman for it contains the orders of the Prophet (ﷺ) concerning the Sadaqa.' "

قَالَ الْحُمَيْدِيُّ حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا مُحَمَّدُ بْنُ سُوقَةَ، قَالَ سَمِعْتُ مُنْذِرًا الثَّوْرِيَّ، عَنِ ابْنِ الْحَنَفِيَّةِ، قَالَ أَرْسَلَنِي أَبِي، خُذْ هَذَا الْكِتَابَ فَاذْهَبْ بِهِ إِلَى عُثْمَانَ، فَإِنَّ فِيهِ أَمْرَ النَّبِيِّ صلى الله عليه وسلم فِي الصَّدَقَةِ‏.‏
