سنن النسائي

It was narrated from Abu Al-Husain Al-Haitham bin Shufayy that he said: "A friend of mine who was called Abu 'Amir, from Al-Ma'afir, and I went out to pray in Jerusalem. Their preacher was a man from (the tribe of) Azd who was called Abu Raihanah, one of the Companions." Abu Al-Husain said: "My companion reached the Masjid before I did, then I caught up with him, and sat beside him. He said: 'Have you heard the preaching of Abu Raihanah?' I said: 'No.' He said: 'I heard him say: 'The Messenger of Allah (ﷺ) [SAW] forbade ten things: Filing (the teeth), tattoos, plucking (hair), for two men to lie under one cover with no barrier between them, for two women to lie under one cover with no barrier between them, for a man to add more than four fingers' width of silk to the bottom of his garment like the foreigners (Persians), (and he forbade) plundering, riding (while sitting on) leopard skins and wearing rings- except for rulers."
