question #3 Sahih al-Bukhari 5852, Book 77, Hadith 69 : Why are certain dyes like saffron or wars prohibited for those in the state of Ihram?

Allah’s Messenger (ﷺ) forbade that a Muhrim should wear clothes dyed with Saffron or Wars, and said,
“Whoever has no shoes can put on Khuffs (socks made from thick fabric or leather) after cutting it
below the ankles.”
