question #1 Sahih al-Bukhari 1841, Book 28, Hadith 21 : What alternatives are permissible for a Muhrim if traditional pilgrimage attire is unavailable?

I heard the Prophet (ﷺ) delivering a sermon at `Arafat saying, “If a Muhrim does not find slippers, he
could wear Khuffs (socks made from thick fabric or leather, but he has to cut short the Khuffs below
the ankles), and if he does not find an Izar (a waist sheet for wrapping the lower half of the body) he
could wear trousers.”
