He emigrated to the Messenger of Allah ﷺ, who asked him, "What is your name?"He replied, "Zahm."The Prophet said, "Rather, you are Bashir."He said, "While I was walking with the Messenger of Allah ﷺ, he passed by the graves of the polytheists and said, 'These people have missed out on much good,' three times. Then he passed by the graves of the Muslims and said, 'These people have attained much good.'Then the Messenger of Allah ﷺ happened to glance and saw a man walking among the graves wearing sandals. He said, 'You there, wearing the sibtiyya sandals, woe to you, take off your sandals!'The man looked, and when he recognized the Messenger of Allah ﷺ, he removed them and threw them aside."
اسم بشير بن الخصاصية في الجاهلية زحم بن معبد
فهاجر إلى رسول الله ﷺ، فقال: ما اسمك؟ قال: زحم، قال: بل أنت بشير- قال: بينما أنا أمشي مع رسول الله ﷺ مر بقبور المشركين فقال: لقد سبق هؤلاء خيرا كثيرا ثلاثا، ثم مر بقبور المسلمين فقال: لقد أدرك هؤلاء خيرا كثيرا وحانت من رسول الله ﷺ نظرة فإذا رجل يمشي في القبور عليه نعلان فقال: يا صاحب السبتيتين ويحك ألق سبتيتيك، فنظر الرجل، فلما عرف رسول الله ﷺ خلعهما فرمى بهما.
Narrated by Abu Dawud (3230), Nasai (2048), and Ibn Majah (1568), all through the route of Aswad bin Shayban, from Khalid bin Samir, from Bashir bin Nuhayk, from Bashir bin Khassasiya, who related it, and their wording is close to one another. Its chain is hasan because of Khalid bin Samir, for he is hasan al-hadith, and Nasai and Ajli both deemed him reliable.It was also recorded by Ibn Hibban (3170), Hakim (1/373), and Imam Ahmad (20787), all through this same route. Hakim said, "Its chain is sahih." Hafiz bin Qayyim, in Tahzib Sunan (4/34-345), relates from Imam Ahmad that he said, "Its chain is good, this is my view, unless there is some defect."His son Abdullah relates in his father's Masail, saying, "I saw him, when he intended to go out to a funeral, put on his leather socks, and he used to command that sandals be removed in graveyards, and he said, 'The hadith of Bashir bin Khassasiya is a hadith of the Prophet ﷺ.'" He said, "I saw my father at a funeral looking at a neighbor who was wearing his sandals and walking among the graves, looking at him as though he disapproved of what he was doing." He also said, "I saw my father, when he intended to enter the graveyards, take off his sandals, and sometimes I saw him, when he intended to go to a funeral, most often put on his leather socks and remove his sandals." See Masail of Imam Ahmad (679-681).As for his statement about "sibtiyyah," it is derived from "sabt," which refers to cowhide tanned with qaraz (a tanning agent), from which sandals are made, so called because its hair had been "subita," meaning shaved and removed.
