Book 57: One-fifth of Booty to the Cause of Allah (Khumus)
Chapter 5 What has been said regarding the armour of the Prophet (ﷺ) ﷺ, his staff, sword, cup and ring, and what the caliphs after him used of these things which had not been distributed, and also (what is said) about his hair, shoes and utensils which were considered as blessed things by his companions and others after his death
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 3107
Narrated `Isa bin Tahman:
Anas brought out to us two worn out leather shoes without hair and with pieces of leather straps. Later
on Thabit Al-Banani told me that Anas said that they were the shoes of the Prophet.
