Read the English translation first, with the original Arabic directly underneath.
Narrated `Abdullah bin `Umar:
A man asked, "O Allah's Messenger (ﷺ) ! What kind of clothes should a Muhrim wear?" Allah's Messenger (ﷺ) replied, "He should not wear a shirt, a turban, trousers, a headcloak or leather socks except if he can find no slippers, he then may wear leather socks after cutting off what might cover the ankles. And he should not wear clothes which are scented with saffron or Wars (kinds of Perfumes) . "
