I saw seventy of the People of the Suffah, and not one of them had an upper garment. Each wore either a waist-wrap or a cloak tied around his neck. Some of these reached halfway down the shins, others reached the ankles, and a man would gather his garment with his hand, not wanting his private parts to be exposed.
رأيت سبعين من أصحاب الصفة، ما منهم رجل عليه رداء، إما إزار وإما كساء، قد ربطوا في أعناقهم، فمنها ما يبلغ نصف الساقين، ومنها ما يبلغ الكعبين، فيجمعه بيده كراهية أن ترى عورته.
Bukhari narrated it in the chapter on prayer (442), from Yusuf bin Isa, who said, our teacher was Ibn Fudayl, from his father, from Abu Hazim, from Abu Hurairah, who related it.His statement, "I saw seventy of the people of the Suffah," Ibn Hajar said in Fath al-Bari (1/536), "This suggests that they were more than seventy, and these whom Abu Hurairah saw were different from the seventy whom the Prophet ﷺ sent in the expedition of Bir Mauna. They too were among the people of the Suffah, but they were martyred before Abu Hurairah embraced Islam."
