(9) باب الصَّلاَةِ فِي الْقَمِيصِ وَالسَّرَاوِيلِ وَالتُّبَّانِ وَالْقَبَاءِ
Narrated Ibn `Umar:
A person asked Allah's Messenger (ﷺ), "What should a Muhrim wear?" He replied, "He should not wear shirts, trousers, a burnus (a hooded cloak), or clothes which are stained with saffron or Wars (a kind of perfume). Whoever does not find a sandal to wear can wear Khuffs (socks made from thick fabric or leather), but these should be cut short so as not to cover the ankles.
