Riyad as-Salihin 468
Abu Hurairah (May allah be pleased with him) reported:
I saw seventy of the people of the Suffah and none of them had a cloak. They had either a lower garment or a blanket which they suspended from their necks. Some (cloaks) reached halfway down to the legs and some to the ankles; and the man would manage to keep it in his hand to avoid exposing his private parts. [Al- Bukhari] .
وعنه، رضي الله عنه، قال‏:‏ لقد رأيت سبعين من أهل الصفة، ما منهم رجل عليه رداء، إما إزار وأما كساء، قد ربطوا في أعناقهم، فمنها ما يبلغ نصف الساقين، ومنها ما يبلغ الكعبين، فيجمعه بيده كراهية أن ترى عورته” ‏(‏‏(‏رواه البخاري‏)‏‏)‏‏.‏
