Yazid bin Zari' يزيد بن زريع · The Book of Hajj

'Pants (are allowed) for one who cannot find an Izar, and Khuffs for one who cannot find sandals to wear in Ihram.;;

'Whoever cannot find an Izar, let him wear pants, and whoever cannot find sandals, let him wear khuffs."

a man asked the Messenger of Allah what clothes the Muhrim should wear? The Messenger of Allah said: "Do not wear shirts, or 'Imamahs, or pants, or burnouses, or Khuffs except if someone does not have sandals, in which case let him wear Khuffs, and cut them so that they come below the ankles. And do not wear any garment that has been touched by (dyed with) saffron or Wars.

"The Messenger of Allah said: "There are five animals all of which are vermin and may be killed inside the sanctuary: Crow, kites, vicious dogs, mice and scorpions.'"

"I saw the Messenger of Allah stoning JamratualAqabah on the Day of Sacrifice on the reddish-brown camel of his, without beating anyone or driving them off."
